Although, CCleaner empties the files of content, I used Linux to delete the three I mentioned originally. I just feel better seeing the new Index.dat files with the smaller sizes. Thanks for the additional information.

"There was a time when CCleaner "marked for deletion" and then got zapped - and immediately recreated by Windows. I believe they now have the contents "vacuumed" in situ." I had to investigate the contents. It appears you are correct that the contents get deleted ("vacuumed") but not the empty files themselves. I would like to state, that I don't feel comfortable with that arrangement. Can that empty filespace be wiped with the filename still in place? "and then got zapped" If you understand how the IE cache works, yes, they would be zapped but they were needed files, so new ones would be created by Windows. Those are data files that contain necessary information (URLs)for the IE cache to function. (Unless you choose privacy mode). I'd like to know why the decision to delete the contents was decided over the deletion of the entire file?

"How can you tell ?" New, empty Index.dats are 16KB to 65KB, depending on location. "Does it matter ?" Depends. No program that claims to clean the items that CCleaner does would be complete without cleaning ALL index.dat files. The ones I listed are hands-down the most important. I use CCleaner rather than a bunch of individual Windows cleaning apps because it is "one-click" cleans all. I expect all. If you don't expect everything to be cleaned, especially when you place a checkmark next to the item, then you think differently than anyone I know.

Have you installed IE9? That seems to be a common complaint of IE9 causing bold/large and/or ClearType problems. Both in programs and websites. You might browse Microsoft Answers/Internet Explorer forum if the solution isn't found here.

Vista Ultimate/IE9 CCleaner v3.05.1408 I can't say if there are other places that CCleaner isn't deleting files but checking several times, these Index.dat files are not being deleted on reboot. C:\Users\UserAccount\AppData\Local\Microsoft\Windows\History\History.IE5\Index.dat (Currently over 835KB) C:\Users\UserAccount\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\Index.dat (Currently at over 3,200KB). C:\Users\UserAccount\AppData\Roaming\Microsoft\Windows\Cookies\Index.dat (Currently over 81KB)

Just recently downloaded/installed: CCleaner v3.04.1389 Vista Ultimate/IE9 IE9 installed March 14, 2011 Was using older version of CCleaner and with IE9, it would not keep me signed-in to websites even though it worked fine with IE8. New version keeping me signed in but doesn't clean Temporary Internet Files and Index.dat in this location: C:\Users\ -User Account-\AppData\Local\temp\Temporary Internet Files Cookies,History,TIF were all moved recently, not sure if related to IE9 or to new version of CCleaner. Old location was here: C:\Users\ -User Account-\AppData\Local\Microsoft\Windows\ Temporary Internet Files When you access TIF through Internet Options, everything is deleted, except for cookies designated to keep: C:\Users\ -User Account-\AppData\Local\Microsoft\Windows\Temporary Internet Files Items checked off for cleaning with CCleaner Under: Internet Explorer heading - everything checked except saved passwords Windows Explorer heading - everything checked System heading - everything checked down to and including Windows Log Files Advanced heading - two items: Old Prefetch Data and Custom Files And Folders. Let me know what steps to follow to fix.
