The virtual machine running my WSUS got a little stuffed. So I decided to move the WSUS data to a fileserver, where the price per MB is a lot lower.
"C:\Program Files\Update Services\Tools\wsusutil.exe" movecontent [newpath] [logfile]
"C:\Program Files\Update Services\Tools\wsusutil.exe" movecontent \\fileserver\wsusdata$\ c:\wsusmove.txt
Of course this very same method can be used to move from c: to d: or something.
