Disk Cleanup Won T Open
Disk Cleanup Not Working Windows 8
Why Doesn’t Disk Cleanup Delete All Files?The applications that you’re running create temporary files, not to litter your hard drive, but to store files while the application is working on them—whether it’s downloading files, storing files that you’re currently editing, or just caching files so the next time you open the application the files will be more quickly accessible.The problem is that most applications don’t seem to clean up after themselves, or if they do, they definitely don’t do it very well. That’s why your temporary folder gets really huge over time, and needs to be cleaned out.Since these files are often being used by applications, Windows doesn’t know whether a particular file can be deleted, so Disk Cleanup only cleans up files that are older than 7 days, which is a safe guess—most people probably don’t have an application open for more than a week, especially since Microsoft makes you reboot nearly every Tuesday, right?You can even see in the screenshot that Disk Cleanup explains this to you, if you select the Temporary files option in the list. Change Disk Cleanup to Delete Files Newer than 7 DaysIf you’re one of those people that reboots your PC every day, you can probably change the Disk Cleanup value down to something lower, like 2 days.
