Disc Cleanup won't delete files

When I run Disk clean-up on C drive, it shows I could free up 48KB of space by deleting Web Client/Publisher Temporary Files. When I check it and hit "OK" (only other choice being "Close") it does not delete. If I check it and highlight it, I get message that these files are blah, blah,blah, but can be safely deleted. Again my 2 choices are "OK" or "Close". I hit "OK" it switches to a screen that moves so fast I can't read it (supposedly deleting these files), but when I check back - THEY ARE STILL THERE! I have even shut down my computer and restarted it and when I run disk cleanup - the files are still there. Help Please?????:tas

 

Yeah, 48k is really, REALLY a tiny amount of space and is really nothing to even have the slightest worries about, but I think the reason the folders aren't being deleted permanently is that as soon as Disk Cleanup removes the folder, it is promptly re-created for whatever reason by the program that uses it. If you're really concerned about a measly 48k, try running the cleanup in Safe Mode. But when you restart in normal mode, the folder will probably return....
