How to Remove Thumbnail Cache on Linux

Before You Clean

Desktop thumbnail caches help file managers show previews quickly. Removing them can free some space, but thumbnails will be regenerated.

Review and Clean Manually

1. Confirm the thumbnail cache is significant compared with other storage use.

2. Close file managers and finish working with the affected files.

3. Use your desktop’s supported thumbnail or cache controls when available. If inspecting a cache directory, distinguish thumbnails from the original images and videos.

4. Review only the thumbnail cache target; do not delete the whole ~/.cache tree.

5. Reopen the file manager and expect thumbnails to rebuild. Check the originals are intact.

Where Kudu Helps

Kudu lists Thumbnail Cache on Linux. Review that specific target and expect the file manager to regenerate previews. Cache cleanup does not remove the source photos or videos.

Open Clean up > System Cleaner and run Scan. Review the relevant category and expand its results to inspect the paths. Set exclusions for anything you need to keep, then check the full selected total before Clean. Results search filters the view; it does not erase selections elsewhere.

After cleaning, check the summary and Activity > Cleanup receipts for removed, skipped, or failed items. A receipt is an outcome record, not a backup. Recovery Centre restores supported settings, not deleted files. Compare actual disk free space and test the original symptom; cache removal alone is not a promise of better performance.
