Are you running out of space on your Windows PC and wants to empty Recycle Bins of all the user logins without logging into every account individually? Here is a quick DOS command to do that
Windows 7/Server 2008
rd /s c:\$Recycle.Bin
Windows XP, Vista, or Server 2003
rd /s c:\recycler
Depending on the operating system version you are using, run one of the following commands in administrative mode to empty all Recycle Bins. We assume that your OS installed on C drive, if not change the drive letter in the above commands.
