Thumbnail Cache - Clear and Reset

How to Clear and Reset Thumbnail Cache in Windows


   Information
By default, Windows stores the images for thumbnail previews in cache memory so that it can redisplay the images quickly each time you reopen a folder in Windows Explorer (Vista and Windows 7) or File Explorer (Windows 8).

This tutorial will show you how you to clear and reset the thumbnail cache to force Windows to reload the thumbnail picture views into the cache again as needed as you open folders.

   Note
The thumbnail cache .db files are located in the hidden system folder location below:

C:\Users\User-Name\AppData\Local\Microsoft\Windows\Explorer

You may want to clear the thumbnail cache if the Windows Explorer thumbnail pictures have become corrupted and not displaying properly, or the thumbnail cache file has become to large and you want to clear some hard disk space.

Hello S.Orangzeb,

You're welcome. I'm not sure about Photoshop though. That subject may be best posted in the Music, Pictures & Video forum area instead.

Hey Gary,

You might see if deleting the individual hidden Thumbs.db files listed in your screenshot may be able to finish them off. :)

Well that worked. Do you have any insight why the Disk clean up, and CCleaner didn't root them out?

Great news. :party:

Disk Cleanup only clears the main central thumbs.db cache in the hidden folder below.

If you like, you might test to see if refreshing (F5), renaming the files, or move them to another location and back may toggle it to show the correct thumbnail.

Moving it somewhere else and it shows correct thumbnail. Moving it backwards and the issue is back.

My Waterfox shortcut on the desktop is still completely black. I tried the batch file, no luck. I loaded Disk Cleanup but the option to clear the thumbnail cache is not there. No luck with CCleaner either.

EDIT
And now, the CCleaner shortcut itself is all black, along with the IObit Uninstaller icon.

EDIT
Each time I create a new shortcut on the desktop, it immediately turns black.
