Make Disk Cleanup Tool deletes ALL temporary files, including those created within the last 7 days

RECOMMENDED: Click here to fix Windows errors and optimize system performance

Many of us still prefer the integrated disk cleaning tool. However, if you use the tool to delete unnecessary and temporary files, some files may still exist in the temporary folder. This is because by default Windows does not delete temporary files (.tmp) in the folder %WinDir%Temp and other folders created or accessed in the last 7 days.

Files may refer to something you download or modify. They may even be linked to an application that is still open. Windows plays security and does not delete temporary files that are less than 7 days old.

But if you wish, you can set the disk cleaning tool to delete all files from temporary folders.
