spywriter007 Posted December 16, 2013 Share Posted December 16, 2013 Hi Everyone, I wish CCleaner would improve the cleaning of Internet Explorer 10 & 11 as index.dat is no longer being used. Apparently Microsoft as renamed the file WebcacheV01.dat. Sometimes this dat file can become corrupted and so deleting it periodically can be useful. There is discussion about this WebcacheV01.dat on another forum. See the link below http://www.sevenforums.com/browsers-mail/311407-ie10-uses-webcachev01-dat-vs-index-dat-files-how-clear-delete.html Cricket Link to comment Share on other sites More sharing options...
Winapp2.ini Posted December 17, 2013 Share Posted December 17, 2013 I've tried more than once to delete that file with no success. winapp2.ini additions thread winapp2.ini github Link to comment Share on other sites More sharing options...
spywriter007 Posted December 17, 2013 Author Share Posted December 17, 2013 Winapp, Are you referring to index.dat or WebcacheV01.dat? CCleaner will delete index.dat but IE 8 and 9 will rebuild this file. I assume the same is true for WebcacheV01.dat... if you manually delete it. Right now though CCleaner does not give you a way to delete that file with their program. Cricket Link to comment Share on other sites More sharing options...

Mel2 Posted December 29, 2013 Share Posted December 29, 2013 I've tried more than once to delete that file with no success. Try using SuperDelete, it comes with SuperAntiSpyware. Link to comment Share on other sites More sharing options...
Alan_B Posted December 30, 2013 Share Posted December 30, 2013 Try using SuperDelete, it comes with SuperAntiSpyware. Alternatively you could try using iCacls to take ownership of any file that Windows thinks it really needs That has a good chance of removing such files and allowing you to discover that Windows was right and it really needed that file I prefer that CCleaner continue to play safe - not many CCleaner users have the skills to repair damage by super access tools. But as ever, the developers will choose what suggestions to accept. Link to comment Share on other sites More sharing options...
foxyshadis Posted June 3, 2015 Share Posted June 3, 2015 Here is the method of cleaning that won't crash your applications or corrupt your hard drive: schtasks /end /tn \Microsoft\Windows\Wininet\CacheTask esentutl /r V01 /l%localappdata%\Microsoft\Windows\WebCache /s%localappdata%\Microsoft\Windows\WebCache del %localappdata%\Microsoft\Windows\WebCache\*.chk del %localappdata%\Microsoft\Windows\WebCache\*.log del %localappdata%\Microsoft\Windows\WebCache\*.jrs esentutl /d %localappdata%\Microsoft\Windows\WebCache\WebCacheV01.dat schtasks /run /tn \Microsoft\Windows\Wininet\CacheTask You don't even need to reboot, though to be on the safe side you might restart IE, Teamviewer, and anything else connecting to taskhostex's Webcache. You do not need to be admin to run this. Explanation: schtasks /end will unlock the file esentutl /r will merge the transaction log into the database, then you can delete the transaction logs esentutl /d will compact the file schtasks /run will turn it back on again Unlocking a file without ensuring the handle is closed in the host appis a Bad Idea, that will quietly or not-so-quietly break something random (as soon as the handle is re-used for another file, the old app will start writing garbage into it thinking it's still the unlocked file).

Moderators Nergal Posted June 3, 2015 Moderators Share Posted June 3, 2015 Old topic is old. I'm not even sure the answer you gave is valid or safe. But threadcromancy is not really needed in this case, so I've closed thread ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.
