If third party tools are used, you can also manually set the passes required.

Defrag can take anywhere from 1-2 passes to more than 30. After each pass, your hard drive becomes more organized and faster to access. It does a rough pass at first and refines it the next time.

Them and the Temporary Internet Files and CustomDestination files that show up whether one uses IE or not. Defragmentation also does the tasks in passes. So everyday or two, I zap them certainly before my weekly backup. I'm not actually sure if there is any compelling reason to delete the WebCache files. Or you can learn how to run cmd under SYSTEM privileges and use the del command on the file(s). A reboot will free up the files so they can be deleted (unless you're running something at startup that runs the process as SYSTEM and writes those files). Unfortunately, occasionally either process could run as SYSTEM and generally you can't End even under an admin account. And those WebCache files will eventually return. They'll just re-start themselves when they need to. CCleaner won't display (or clean) files in use.Īs for either of those two processes, if in Task Manager you see they're running under your user account, you can End without issue and delete the dat file.

There are times the dat file isn't listed and that's when I find it to be locked. Under that, the WebCache files are found - chk, log, jrs - and that V01.dat file, sometimes. I use CCleaner, CCEnhancer and winapp2.ini, the latter two add (among a bunch of others) an 'Internet - Internet Explorer 10/11' item for cleaning.

This has been my experience (in Windows 7 圆4) even though I don't use IE.
