Delete WebCacheV01.dat with "WebCacheV01.dat Viewer & Deleter" Hello, As you may know, Internet Explorer 10 and above uses a new Web Cache technology to index and store cookies and websites you have visited. Old index.dat files are replaced by an ESE database (WebCacheV01.dat or WebCacheV24.dat) located in %LOCALAPPDATA%\Microsoft\Windows\WebCache For more information on ESE database (Jet Blue database), see here : http://en.wikipedia.org/wiki/Extensible_Storage_Engine What we know so far, after investigations : 1. Cookies, visited websites, DOM Storages are indexed in WebCacheV01.dat 2. Not only IE uses WebCacheV01.dat, Windows apps may use it too to store cookies and DOM Storages 3. WebCacheV01.dat is locked by taskhost.exe, making it hard to delete 4. WebCacheV01.dat is only released after user logoff Anyway, after days of investigation, we have finally found a way to delete WebCacheV01.dat and preserve your privacy. To give you full access to WebCacheV01.dat, we intend to develop a new software called "WebCacheV01.dat Viewer & Deleter". You will be able to : - view containers/ entries in WebCacheV01.dat - delete entries in WebCacheV01.dat - delete WebCacheV01.dat Thanks for your feedback.
