# Is MEMORY.DMP Safe to Delete in Windows 11? > Can you safely delete MEMORY.DMP? Learn what Windows crash dumps contain, how to check their size, and how to remove old dumps without losing important data. URL: https://raincleaner.eu/guides/memory-dmp-safe-to-delete-windows-11 Short answer: MEMORY.DMP is generally safe to delete after a Windows crash has finished and the file is no longer needed for diagnosis, but removing it permanently discards that crash's diagnostic memory snapshot. ## What Is MEMORY.DMP in Windows 11? MEMORY.DMP is a Windows crash dump file that can be created when the operating system encounters a serious failure, commonly called a stop error or Blue Screen of Death. A crash dump captures selected information from system memory at the time of the failure. The amount and type of information depend on the configured dump format. Windows and debugging tools can use this information to investigate malfunctioning drivers, kernel failures, memory-related problems, and other causes of unexpected system crashes. The default location for kernel, automatic, active, and complete crash dumps is %SystemRoot%\MEMORY.DMP. On a standard installation where Windows is located at C:\Windows, the default path is C:\Windows\MEMORY.DMP. The location is configurable. A computer may store its crash dump on another drive or use a different filename. MEMORY.DMP is not a Windows executable, installed driver, personal document, or ordinary temporary internet file. It is diagnostic evidence. Windows does not normally require an old completed MEMORY.DMP file to run applications or start successfully. Deleting the existing dump does not disable future crash dump creation. Windows may create another dump if a qualifying system failure occurs and crash dump collection is configured correctly. Microsoft documents the default crash dump locations at https://learn.microsoft.com/en-us/windows/client-management/troubleshoot-stop-errors. ## Why Is MEMORY.DMP So Large? The size of MEMORY.DMP depends primarily on the type of crash dump Windows is configured to create and the memory information collected during the failure. A complete memory dump can contain almost all physical memory used by Windows at the time of the crash. On a computer with substantial RAM, this can produce a very large file. A kernel memory dump focuses on memory used by the Windows kernel, hardware abstraction layer, and kernel-mode components. It is generally smaller than a complete memory dump. An automatic memory dump contains the same diagnostic information as a kernel memory dump. Its main difference is how Windows manages the system paging file to support crash dump collection. An active memory dump includes selected active memory pages that are useful for debugging while excluding certain memory regions considered less relevant. A small memory dump contains a much smaller amount of diagnostic information and is normally stored in a separate directory. Because these formats contain different amounts of information, there is no universal MEMORY.DMP file size. A large dump is not necessarily corrupted or unnecessary. Its size may be appropriate for the configured diagnostic format. Microsoft explains these formats at https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/varieties-of-kernel-mode-dump-files. - Complete memory dump: Captures extensive physical memory information and may occupy substantial disk space. - Kernel memory dump: Captures memory associated with the Windows kernel and kernel-mode components. - Automatic memory dump: Contains kernel dump information while allowing Windows to manage paging file requirements differently. - Active memory dump: Captures selected active memory useful for investigating system failures. - Small memory dump: Stores a limited diagnostic record, normally under %SystemRoot%\Minidump. - A larger dump can provide more diagnostic detail but is not automatically more useful for every problem. ## How to Check the MEMORY.DMP Location Before inspecting or deleting a crash dump, verify your Windows version and the configured dump file location. Step 1: Press Win + R, type winver, and press Enter. Step 2: Record your Windows version and OS build. Step 3: Press Win + R, type cmd, and press Enter to open Command Prompt. Step 4: Run echo %SystemRoot% to identify the active Windows installation directory. Step 5: Run dir /a "%SystemRoot%\MEMORY.DMP" to check whether a dump exists at the default location. Step 6: If the file exists, Command Prompt will display its filename, size, and modification date. Step 7: If Windows reports File Not Found, the dump may not exist or may be stored at a custom location. Step 8: Press Win + R, enter SystemPropertiesAdvanced.exe, and press Enter. Step 9: Under Startup and Recovery, select Settings. Step 10: Review the Write debugging information dropdown and the Dump file field where available. Step 11: Record the configured dump type and file location. Step 12: Do not modify these settings simply to inspect the existing configuration. The Startup and Recovery dialog is the preferred graphical location for checking the active crash dump configuration. The actual directory may differ from the default when an administrator or system-management tool has configured a custom destination. Do not assume that every file named MEMORY.DMP on another drive belongs to the current Windows installation. ## How to Check MEMORY.DMP Size and Date Checking a dump's size and modification date helps determine whether it is a significant source of disk usage and whether it may relate to a recent crash. Step 1: Open File Explorer. Step 2: Enter %SystemRoot% in the address bar and press Enter. Step 3: Locate MEMORY.DMP if it exists at the default location. Step 4: Right-click the file and select Properties. Step 5: Review its Size, Size on disk, and Modified information. Step 6: To inspect the default dump using PowerShell, open PowerShell. Step 7: Run $path = Join-Path $env:SystemRoot 'MEMORY.DMP'. Step 8: Run Test-Path -LiteralPath $path to check whether the file exists. Step 9: If the result is True, run Get-Item -LiteralPath $path | Select-Object FullName, Length, LastWriteTime. Step 10: To display its logical size in gigabytes, run (Get-Item -LiteralPath $path).Length / 1GB. These PowerShell commands inspect the file without changing or deleting it. If the configured dump path differs from the default, inspect that exact path instead. The reported logical file size can differ from physical storage usage because of filesystem allocation, compression, or other storage behavior. A recent modification date can help connect a dump with a crash, but the date alone does not establish the cause of the failure. If the file is inaccessible, do not change ownership or permissions merely to measure it. ## When Is It Safe to Delete MEMORY.DMP? An existing MEMORY.DMP file can generally be removed after the system has recovered from the crash and the diagnostic information is no longer needed. For example, if the computer crashed once several months ago, has operated normally since, and no investigation is ongoing, keeping the old dump may provide little practical value. However, a dump created during a recent or recurring blue-screen problem may contain important evidence. If a technician, manufacturer, software developer, or Microsoft support representative is investigating the crash, preserve the dump until the investigation is complete. Do not delete a crash dump while Windows is collecting or writing diagnostic data following a system failure. A completed dump should not be confused with the paging file or other live memory-management components. Deleting a completed MEMORY.DMP does not repair the problem that originally caused the system crash. If the same failure occurs again, Windows may create another dump, provided crash dump collection is enabled and its storage requirements are satisfied. If the computer is managed by an organization, follow its diagnostic retention and incident-response policies before removing crash data. - Generally safe: Deleting an old completed dump when the associated crash no longer requires investigation. - Generally safe: Removing a dump after its diagnostic information has been reviewed and is no longer required. - Generally safe: Using the supported Windows cleanup category for obsolete system error memory dumps. - Keep: A dump associated with an unresolved blue-screen error. - Keep: A dump requested by technical support or a hardware manufacturer. - Keep: A dump required for an active security or incident investigation. - Do not delete: A dump that is actively being collected or written. - Use caution: Dumps stored on organization-managed computers. - Not recommended: Automatically deleting every new dump before the cause of recurring crashes has been identified. ## Method 1: Delete Old Memory Dumps Through Windows Settings Windows 11 includes storage cleanup tools that may offer a category for system error memory dump files. This is the preferred approach for ordinary users because Windows identifies files belonging to supported cleanup categories. Step 1: Save your work and make sure Windows is not currently collecting crash diagnostics. Step 2: Press Win + I to open Settings. Step 3: Navigate to System > Storage. Step 4: Open Temporary files. Step 5: Allow Windows to calculate the available cleanup categories. Step 6: Look for System error memory dump files or a similarly named category describing system crash dumps. Step 7: Review the reported size and confirm that you no longer need the diagnostic data. Step 8: If you intend to remove only crash dumps, deselect unrelated cleanup categories. Step 9: Pay particular attention to Downloads, Recycle Bin, and other categories that may contain personal files. Step 10: Select the appropriate dump cleanup category and choose Remove files. Step 11: Confirm the cleanup when prompted. Step 12: Wait for Windows to finish. Step 13: Return to File Explorer > This PC and check the available space on the system drive. The exact categories displayed depend on the Windows version, installed components, and available diagnostic files. If no system error memory dump category appears, do not assume the computer is malfunctioning. The category may be empty or unavailable on the current configuration. The cleanup operation may not include every dump stored in a custom directory. Do not select unrelated cleanup categories merely because the desired category is missing. Microsoft's Windows storage guidance is available at https://support.microsoft.com/en-us/windows/experience/storage-filemanagement/free-up-drive-space-in-windows. ## Method 2: Use Windows Disk Cleanup The traditional Disk Cleanup utility can also provide an option for removing system error memory dump files. Step 1: Press Win + R. Step 2: Type cleanmgr and press Enter. Step 3: If prompted to choose a drive, select the drive containing the active Windows installation. Step 4: To verify the system drive, open Command Prompt and run echo %SystemDrive%. Step 5: Wait for Disk Cleanup to calculate available cleanup categories. Step 6: Select Clean up system files if that option is available. Step 7: Review the recalculated list of cleanup categories. Step 8: Look for System error memory dump files. Step 9: If the category is present, review its reported size. Step 10: Select the category only after confirming that the associated diagnostic information is no longer required. Step 11: Deselect unrelated categories if you intend to remove only memory dumps. Step 12: Click OK and confirm Delete Files. Step 13: Wait for cleanup to finish. Step 14: Check the available disk space through File Explorer > This PC. Disk Cleanup may also display System error minidump files as a separate category. A minidump is not the same as the larger MEMORY.DMP file. Review the categories separately. The availability and naming of these categories can vary depending on Windows configuration and the files currently present. Disk Cleanup does not guarantee removal of custom dump files stored outside its supported cleanup locations. Do not remove unrelated diagnostic files when troubleshooting is still in progress. ## Method 3: Remove a Verified Old MEMORY.DMP Manually Manual removal is an alternative when Windows cleanup tools do not provide the required category and you have positively identified an obsolete dump file. Use this method only for a specific completed MEMORY.DMP file that is no longer needed. Step 1: Confirm that the computer is operating normally and no crash dump collection is in progress. Step 2: Open the Startup and Recovery settings through SystemPropertiesAdvanced.exe. Step 3: Record the configured Dump file path. Step 4: Open File Explorer and navigate to that exact location. Step 5: Verify the filename, file size, and modification date. Step 6: Confirm that the dump is not required for a current troubleshooting or support investigation. Step 7: If you need the diagnostic evidence later, preserve a copy in an appropriately secured location before removing the original. Step 8: Select only the verified MEMORY.DMP file. Step 9: Use File Explorer's Delete command. Step 10: If Windows requests administrator authorization, proceed only if you are authorized to manage the computer. Step 11: Do not change folder ownership, disable security features, or force deletion if Windows refuses access. Step 12: Check whether the file was removed and compare the available disk space. Do not select the entire Windows directory or other crash-dump-related folders. Do not delete pagefile.sys, swapfile.sys, or hiberfil.sys as part of this procedure. If the file is currently locked or unavailable, stop rather than attempting to bypass Windows protections. A normal file deletion may send the dump to the Recycle Bin depending on the deletion method and location. Emptying the Recycle Bin permanently removes the file and may be necessary before its allocated disk space is fully recovered. Manually deleting a specific dump does not change the existing crash dump configuration. Windows may create a new MEMORY.DMP after another qualifying system crash. ## How to Check Windows Crash Dump Settings Windows provides several crash dump formats. The current selection determines what diagnostic information Windows attempts to collect after a qualifying system failure. Step 1: Press Win + R. Step 2: Enter SystemPropertiesAdvanced.exe and press Enter. Step 3: Open the Advanced tab if it is not already selected. Step 4: Under Startup and Recovery, select Settings. Step 5: Locate Write debugging information. Step 6: Review the selected option without changing it. Step 7: Inspect the Dump file path shown in the dialog when applicable. Step 8: Review the Overwrite any existing file option when available. Step 9: Close the dialog without making changes. Windows may offer Small memory dump, Kernel memory dump, Complete memory dump, Automatic memory dump, Active memory dump, or no debugging information, depending on the version and configuration. The Overwrite any existing file setting controls whether supported dump formats can replace a previous dump at the configured destination. A computer configured for Small memory dump typically stores its small dumps under %SystemRoot%\Minidump rather than creating a large MEMORY.DMP for that format. Crash dump collection also depends on sufficient storage and appropriate paging or dedicated dump file configuration. Do not disable crash dump collection solely to prevent MEMORY.DMP from using disk space. This can remove important diagnostic capabilities. Microsoft documents crash dump configuration at https://learn.microsoft.com/en-us/troubleshoot/windows-client/performance/configure-system-failure-and-recovery-options. ## How to Inspect Crash Dump Settings with Commands Advanced users can inspect the configured crash dump settings using read-only registry queries. The relevant registry location is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl. Step 1: Open Command Prompt. Step 2: Run reg query "HKLM\SYSTEM\CurrentControlSet\Control\CrashControl" /v CrashDumpEnabled. Step 3: Run reg query "HKLM\SYSTEM\CurrentControlSet\Control\CrashControl" /v DumpFile. Step 4: Run reg query "HKLM\SYSTEM\CurrentControlSet\Control\CrashControl" /v MinidumpDir. Step 5: Run reg query "HKLM\SYSTEM\CurrentControlSet\Control\CrashControl" /v Overwrite. The CrashDumpEnabled value identifies the configured crash dump mode. Common values include 0 for no crash dump, 1 for a complete dump, 2 for a kernel dump, 3 for a small dump, and 7 for an automatic dump. An active memory dump uses CrashDumpEnabled set to 1 together with the appropriate FilterPages configuration. The DumpFile value identifies the configured location of the larger system crash dump. The MinidumpDir value identifies the configured location for small memory dumps. The Overwrite value indicates whether an existing dump can be overwritten when the applicable crash dump mechanism supports that behavior. If a registry value does not exist, do not create or modify it merely to investigate the configuration. These reg query commands are read-only. They do not enable, disable, generate, or delete crash dumps. The graphical Startup and Recovery settings provide a more accessible way to inspect the configuration. Microsoft documents these registry settings at https://learn.microsoft.com/en-us/troubleshoot/windows-server/performance/memory-dump-file-options. ## MEMORY.DMP vs. Minidump vs. Pagefile.sys MEMORY.DMP, small crash dumps, and the Windows paging file serve different purposes and should not be treated as interchangeable. MEMORY.DMP is commonly a large diagnostic file created after a serious system failure. Small crash dumps are commonly stored under %SystemRoot%\Minidump and contain a limited amount of information about individual crashes. Pagefile.sys is a Windows paging file used by the operating system's virtual memory management. Depending on the configuration, the paging file can also help Windows capture crash dump information when a system failure occurs. The default paging file is commonly located at the root of the system drive, such as C:\pagefile.sys, but its location and size are configurable. To inspect paging file settings, press Win + R, run SystemPropertiesAdvanced.exe, select Performance > Settings, open the Advanced tab, and choose Change under Virtual memory. Deleting an old completed MEMORY.DMP is different from attempting to remove or disable the paging file. Changing paging file settings can affect virtual memory behavior and the ability to capture future crash dumps. Hiberfil.sys is another distinct system file, associated with Windows hibernation and certain power features. Do not delete or disable pagefile.sys or hiberfil.sys as part of crash dump cleanup. If the main objective is freeing disk space, identify the actual file responsible before changing Windows memory-management settings. - MEMORY.DMP: A diagnostic memory snapshot associated with a serious system crash. - Minidump: A smaller crash diagnostic file, commonly stored under %SystemRoot%\Minidump. - Pagefile.sys: A paging file used for Windows virtual memory management and potentially crash dump collection. - Hiberfil.sys: A system file used by Windows hibernation and related power features. - WER reports: Error-reporting records that are not necessarily the same as system crash dumps. - Deleting an obsolete dump does not require disabling virtual memory or crash reporting. ## Safe vs. Unsafe MEMORY.DMP Cleanup Crash dump cleanup is generally straightforward when the file is no longer needed, but some actions can permanently remove valuable diagnostic evidence or interfere with Windows configuration. The safest approach is to inspect the file first and use Windows' supported cleanup tools whenever possible. - Safe: Checking the Windows version with winver. - Safe: Inspecting the default dump path with dir /a "%SystemRoot%\MEMORY.DMP". - Safe: Measuring an existing dump with read-only PowerShell commands. - Safe: Reviewing Startup and Recovery settings without changing them. - Generally safe: Deleting an old completed MEMORY.DMP when no investigation requires it. - Generally safe: Using Windows Storage settings to remove obsolete system error memory dump files. - Generally safe: Using Disk Cleanup after reviewing the exact diagnostic categories selected. - Conditionally safe: Manually deleting a verified obsolete dump from its configured location. - Keep: Dumps associated with unresolved blue-screen failures. - Keep: Dumps required by support technicians, developers, or incident investigators. - Unsafe: Removing a dump while Windows is collecting or writing it. - Unsafe: Deleting unrelated protected Windows system files. - Unsafe: Changing system folder ownership or permissions to force deletion. - Not recommended: Disabling crash dump collection solely to save disk space. - Not recommended: Deleting pagefile.sys or other live memory-management files. - Not recommended: Automatically deleting every new crash dump before diagnosing recurring failures. ## Will Deleting MEMORY.DMP Fix Blue Screen Errors? No. MEMORY.DMP is a record of a crash, not the component that normally causes it. Deleting the file does not repair a defective driver, failing hardware, corrupted system component, or incompatible application. If Windows repeatedly displays a blue-screen error, preserve the existing dump until the problem has been investigated. Step 1: Record the stop code displayed during the crash, when available. Step 2: Press Win + R, enter perfmon /rel, and press Enter to open Reliability Monitor. Step 3: Review the available history for Windows failures or unexpected shutdowns. Step 4: Press Win + R, enter eventvwr.msc, and press Enter. Step 5: Open Windows Logs > System. Step 6: Inspect relevant events around the time of the failure. Step 7: A BugCheck event may provide information about a recorded stop error when one is available. Step 8: A Kernel-Power event such as Event ID 41 can indicate an unexpected restart, but it does not independently identify the original cause. Step 9: Check the modification date of MEMORY.DMP and compare it with the recorded failure. Step 10: If you need detailed crash analysis, use Microsoft-supported debugging tools or obtain qualified technical assistance. Windows Debugger can analyze crash dumps and provide information about stop codes, call stacks, and drivers involved in a failure. Debugging results require interpretation. A driver filename appearing in a crash analysis does not automatically prove that the named driver is defective. Microsoft provides an overview of stop error troubleshooting at https://learn.microsoft.com/en-us/windows/client-management/troubleshoot-stop-errors. Do not remove useful crash evidence simply because the dump file occupies substantial disk space. ## Can MEMORY.DMP Contain Personal Information? Yes. A memory dump may contain sensitive information depending on the dump type and the memory present when Windows crashed. Complete and active memory dumps can contain information from user-mode memory, including data associated with running applications. Kernel memory dumps contain kernel-related memory and may also include information that should be treated as sensitive. The exact contents depend on the Windows configuration and the circumstances of the crash. A dump is not automatically safe to publish or share simply because its filename is MEMORY.DMP. Avoid uploading crash dumps to unknown online analysis services. If a support provider requests a dump, confirm the recipient and use an appropriate secure transfer method. Organizations should apply their diagnostic data retention and information-security policies. If a dump is no longer required, deleting it can reduce the amount of potentially sensitive diagnostic information stored locally. Deleting a local dump does not remove copies that were previously transferred elsewhere. If you preserve a copy for later analysis, store it securely and remove it when the investigation is complete. Microsoft documents the contents of active memory dumps at https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/active-memory-dump. ## How Much Space Will Deleting MEMORY.DMP Recover? There is no guaranteed amount of space that deleting MEMORY.DMP will recover. The available space depends on the existing dump file's actual storage allocation, the dump format, filesystem behavior, and any other files being created or removed at the same time. A complete memory dump can be much larger than a kernel or small dump, but actual sizes vary. Step 1: Open File Explorer > This PC. Step 2: Record the available space on the drive containing MEMORY.DMP. Step 3: Inspect the dump's Size and Size on disk through File Explorer > Properties. Step 4: If using Windows cleanup tools, select only the appropriate system error memory dump category. Step 5: Complete the cleanup and return to File Explorer > This PC. Step 6: Compare the available disk space before and after cleanup. Step 7: If the dump was manually moved to the Recycle Bin, remember that its space may not be fully recovered until the Recycle Bin is emptied. Step 8: If available space does not change as expected, verify whether the original file still exists. Step 9: Check whether Windows or another application created additional files during the same period. The logical size of a file does not always equal the exact amount of physical storage released when it is deleted. Do not attempt to free more space by deleting unrelated Windows system files. If MEMORY.DMP is small or absent, investigate other large files and folders before changing crash dump settings. ## What If MEMORY.DMP Keeps Coming Back? If MEMORY.DMP repeatedly reappears after deletion, Windows may be creating new dumps because additional system crashes are occurring. A new file is not automatically evidence that cleanup failed. Step 1: Run dir /a "%SystemRoot%\MEMORY.DMP" to inspect the default dump's current modification date. Step 2: If a custom dump path is configured, inspect that location instead. Step 3: Open Reliability Monitor using perfmon /rel. Step 4: Check for repeated Windows failures near the dump file's modification date. Step 5: Open Event Viewer with eventvwr.msc and inspect Windows Logs > System. Step 6: Record relevant stop codes, event times, and driver-related messages. Step 7: Check whether the crashes began after a recent driver, Windows, firmware, or hardware change. Step 8: Preserve the newest relevant dump until the underlying problem has been investigated. Step 9: Follow Microsoft or manufacturer troubleshooting procedures appropriate to the observed failure. Windows can overwrite an earlier MEMORY.DMP when a new qualifying dump is created and the configured overwrite behavior permits it. The presence of a new dump after a crash does not mean that Windows restored the previously deleted file. Do not repeatedly delete new dumps while ignoring recurring system failures. If crashes continue, diagnosing the underlying problem is more important than repeatedly recovering the space occupied by its diagnostic records. ## Key Takeaways and Related Guides MEMORY.DMP is a Windows crash diagnostic file, commonly stored at %SystemRoot%\MEMORY.DMP. It can generally be removed after the associated crash has finished and the diagnostic information is no longer needed. Use Windows 11 Settings > System > Storage > Temporary files or cleanmgr when the appropriate system error memory dump category is available. Before deleting a file manually, confirm the configured dump path through SystemPropertiesAdvanced.exe > Startup and Recovery > Settings. Preserve dumps associated with recurring blue-screen errors or ongoing support investigations. Deleting a dump does not repair the underlying system failure and does not prevent Windows from generating future dumps. Do not confuse MEMORY.DMP with pagefile.sys, hiberfil.sys, application crash dumps, or small system minidumps.

An existing completed MEMORY.DMP file can generally be deleted when it is no longer needed for crash analysis. Verify the actual dump location through Startup and Recovery settings and preserve the file if an investigation is ongoing. Why is MEMORY.DMP taking up so much space? MEMORY.DMP contains diagnostic memory information captured during a serious Windows failure. Its size depends on whether Windows created a kernel, automatic, active, or complete memory dump and on the memory information collected. Will deleting MEMORY.DMP make Windows faster? Deleting an old crash dump can recover disk space, but it does not directly improve CPU performance, graphics performance, or application speed. It also does not repair the driver or hardware problem that caused the original crash. Will Windows recreate MEMORY.DMP after I delete it? Windows may create a new MEMORY.DMP if another qualifying system crash occurs and crash dump collection is correctly configured. Deleting an old dump does not disable future crash reporting. Is MEMORY.DMP the same as pagefile.sys? No. MEMORY.DMP is a crash diagnostic file, while pagefile.sys is used for Windows virtual memory management and may help support crash dump collection. Deleting an obsolete dump is different from changing or disabling the Windows paging file. ## Read next - [Free up disk space on Windows 11 safely — Built-in tools first, and what to check before you delete.](https://raincleaner.eu/guides/free-up-disk-space-windows-11-safely) - [Delete temporary files on Windows 11 safely — What is safe to remove, and what needs a second look.](https://raincleaner.eu/guides/delete-temporary-files-windows-11-safely) - [Windows Update Cleanup: is it safe? — What it removes, what you lose, and when to use it.](https://raincleaner.eu/guides/windows-update-cleanup-safe-to-delete-windows-11) - [WinSxS folder too large? — Why it looks so big, and the safe ways to shrink it.](https://raincleaner.eu/guides/winsxs-folder-too-large-what-to-delete-windows-11) - [Windows.old: is it safe to delete? — What it holds, what you lose, and the supported way to remove it.](https://raincleaner.eu/guides/windows-old-safe-to-delete) - [Delivery Optimization files: safe to delete? — What the cache is and how to clear it with Windows tools.](https://raincleaner.eu/guides/delivery-optimization-files-safe-to-delete) - [Find large files on Windows 11](https://raincleaner.eu/guides/find-large-files-taking-space-windows-11) - [Windows cleanup guide](https://raincleaner.eu/guides/windows-cleanup) - [Windows 11 disk cleanup checklist](https://raincleaner.eu/guides/windows-11-disk-cleanup-checklist) - [Before you clean Windows](https://raincleaner.eu/guides/before-cleaning-windows) - [hiberfil.sys and pagefile.sys](https://raincleaner.eu/guides/hiberfil-sys-pagefile-sys-can-you-delete-them) - [Clean Windows with Rain Cleaner, step by step](https://raincleaner.eu/guides/how-to-clean-windows-with-rain-cleaner) - [Windows Update Download Cache](https://raincleaner.eu/guides/softwaredistribution-download-safe-to-delete) - [Why Is System Volume Information So Large?](https://raincleaner.eu/guides/system-volume-information-too-large-windows-11) - [Windows Installer Cache: What Is Safe?](https://raincleaner.eu/guides/windows-installer-folder-safe-to-delete) - [DirectX Shader Cache: Safe Cleanup Guide](https://raincleaner.eu/guides/directx-shader-cache-safe-to-delete-windows-11) - [Windows Error Reporting Files: Safe Cleanup](https://raincleaner.eu/guides/windows-error-reporting-files-safe-to-delete) - [Windows 11 PC health check](https://raincleaner.eu/guides/windows-11-pc-health-check-before-using-a-cleaner) - [Windows 11 slow after an update](https://raincleaner.eu/guides/windows-11-slow-after-update-what-to-check) - [Find a driver by Hardware ID](https://raincleaner.eu/guides/find-driver-by-hardware-id-windows) - [Rain Cleaner vs CCleaner vs BleachBit](https://raincleaner.eu/guides/rain-cleaner-vs-ccleaner-vs-bleachbit) - [Drivers after a clean install of Windows 11](https://raincleaner.eu/guides/drivers-after-clean-install-windows-11) - [Install INF drivers with PnPUtil](https://raincleaner.eu/guides/install-inf-drivers-pnputil-windows-11) - [Free up Android storage safely](https://raincleaner.eu/guides/free-up-storage-android-without-deleting-important-files) - [Find duplicate photos on Android](https://raincleaner.eu/guides/find-and-delete-duplicate-photos-android) - [Windows 11 cleaner without ads](https://raincleaner.eu/windows-11-cleaner) - [Windows protected your PC: verify and run Rain Cleaner](https://raincleaner.eu/windows-protected-your-pc-rain-cleaner) - [Security reporting](https://raincleaner.eu/security) - [Roadmap](https://raincleaner.eu/roadmap) - [Linux server disk full](https://raincleaner.eu/guides/linux-server-disk-full-find-what-is-using-space) - [journald logs too big](https://raincleaner.eu/guides/journald-logs-too-big-limit-journal-size) - [CCleaner alternatives for Windows 11](https://raincleaner.eu/guides/ccleaner-alternatives-windows-11) - [Why Is DriverStore Taking So Much Space?](https://raincleaner.eu/guides/driverstore-filerepository-too-large-windows-11) - [How to Fix Device Manager Code 10](https://raincleaner.eu/guides/device-manager-code-10-device-cannot-start) - [How to Fix Device Manager Code 31](https://raincleaner.eu/guides/device-manager-code-31-windows-cannot-load-drivers) - [How to Fix Device Manager Code 52](https://raincleaner.eu/guides/device-manager-code-52-driver-signature-error)
