it deletes the thumbcache_????.db files where ???? will vary depending on the thumbnail cache in question.

if you aren't seeing any to clean, maybe you either have Always show icons, never thumbnails in Windows Explorer, or you aren't doing whatever generates them.

OR

this site, https://www.raymond.cc/blog/what-you-should-know-about-thumbsdb-file/ reports sometimes CC doesn't do the job, not that I've experienced this first hand.

hi

thanks for the answer

i found this https://www.piriform.com/docs/ccleaner/ccleaner-rules/windows-tab/windows-explorer-files

Thumbnail Cache - This option clears the Windows Explorer image thumbnail cache, which is maintained to speed up the browsing of folders containing photos and images. But it will also contain the thumbnails of images that are no longer on the system. (This rule is for Window Vista only.)

but i don't know if it's related to older version of ccleaner

Mta did you test it ? i mean does it delete thumbcache located here C:\Users\%username%\AppData\Local\Microsoft\Windows\Explorer

i'm running ccleaner last version under w8.1 64 and w7 sp1 64

thanks a lot

Yep, it tests OK on my PC (Win8.1u1 Pro 64bit).

I Analyse, it finds 9 (this time), I Clean, it removes them, Analyse again finds none.

Just thinking outside the box, try running CC with the PC booted in Safe Mode.

And when you say 'last version' i assume you mean v4.17.4808 ?

Have you got that option ticked in Folder Options to not cache thumbnails?

Your Analyse finds 0, is that really true, have you confirmed some thumbs cache files do exist?
