For the times when you’re looking to clean up space on a server and you run a utility like Treesize Free and determine that you have loads of wasted disk space used by various users’ Recycle Bins. Here’s how to clean that up (not to worry, the Recycle Bin directory structure is automatically recreated as it is needed).
To empty all Recycle Bins:
Windows 2003:
rd /s c:\recycler
Windows 2008/2012:
rd /s c:\$Recycle.Bin
