anyone know how to clear thumbnail cashe in windows xp 64bit?
If you have done it in 64bit win xp for sure I would like to know how and would appreciate it.
If you have done it before in XP 32bit or have just a guess please DO NOT answer this topic. I can see those easily over the net.
thanks.

Everything I'm finding is basically saying it's identical on XP32 and XP64 - apologies if I'm wrong on that but nothing's indicating otherwise, just that Vista and Win7 are the ones using a centralized cache - XP does it folder-by-folder.

From what I read about clearing it in xp32 is to first find the thumbs.db after unhiding all your files and delete it etc.
However in my xp64 I unhide everything and I cant find the thumbs.db to delete it so I assume I dont have one.
Or maybe my problem is that I dont have one?
All I know is my photoshop .psd files dont show up as image thumbnails anymore. Other thumbnails of images work.
