How to Clear Windows Thumbnail Cache in Windows 11
You clear your Windows 11 thumbnail cache to resolve corrupted file previews and ensure your icons display correctly.
The thumbnail cache stores small image previews for your files, allowing Windows to show them quickly instead of generating them on the fly. This speeds up browsing folders containing many images or documents.
When this cache gets corrupted, you’ll often see blank or default icons instead of the actual file previews. Fixing this ensures your file explorers load faster and look as they should.
By clearing the cache in Windows 11, you force your PC to rebuild it from the ground up. This process guarantees fresh, accurate thumbnails for all your files, typically resolving display issues.
Clear the Windows thumbnail cache using Disk Cleanup or the Command Prompt. Open File Explorer, right-click your C: drive, select Properties, then Disk Cleanup, and check Thumbnails. Alternatively, use Command Prompt commands to delete thumbcache_*.db files.
Is it safe to clear the thumbnail cache?
Yes, it is completely safe. Clearing the thumbnail cache does not delete your actual photos, videos, or documents. It only removes the temporary preview database files. Windows will automatically rebuild these previews the next time you open a folder containing those files.
How often should I clear the thumbnail cache?
You do not need to clear it regularly. Only perform this task if you notice your folder icons are blurry, missing, or showing incorrect previews. If you find yourself doing this often, it may indicate a deeper issue with your hard drive or system files.
Why this happens: Understanding Cache Corruption
Windows thumbnail cache can get corrupted because the preview files it stores can become mismatched or broken over time, especially as you add or delete files.
Method 1Using Disk Cleanup (Easiest Way)
You can easily clear your Windows 11 thumbnail cache using the built-in Disk Cleanup tool. This handy feature safely removes those temporary preview files that can build up and cause issues.
- Open File Explorer and click This PC.
- Right-click your Local Disk (C:) and select Properties.
- Click the Disk Cleanup button.

Method 2Automated Cleanup via Command Prompt
If you want a faster way to clear the Windows 11 thumbnail cache, you can use a simple Command Prompt command. This method automatically deletes the old preview files, freeing up space.
You must stop the Windows Explorer process first to unlock the files.
del /f /s /q %LocalAppData%\Microsoft\Windows\Explorer\thumbcache_*.dbAfter running these commands, your desktop will disappear briefly. This is normal. Your icons will reappear once the cache is rebuilt.
Troubleshooting: Thumbnails Still Not Working?
If clearing the cache does not fix the issue, check your Folder Options:
- Open File Explorer.
- Click the three dots (…) at the top and select Options.
- Go to the View tab.
- Ensure the box Always show icons, never thumbnails is unchecked.
- Click Apply and OK.
Summary
Clearing the Windows 11 thumbnail cache fixes broken icons by removing old preview files, which Windows then rebuilds automatically using safe methods like Disk Cleanup or Command Prompt.
Will clearing the cache delete my actual image files?
No, clearing the thumbnail cache will not delete your actual image files. It only removes the small, temporary preview images that Windows generates to speed up folder browsing. Your original photos, videos, and documents remain completely untouched and safe on your hard drive.
