THIS WILL FORCE DELETE FILES, USE AT YOUR OWN RISK!!!
This one has hounded me many times, and I thought I already did a KB for this, but apparently not, so here goes;
First make sure everyone is off, I use the MS file sharing MSC, “Share and Storage Management”. On the newer versions of Windows server, you may need to install the feature.
I use robocopy with the /MIR switch;
robocopy /mir c:\<ANY EMPTY DIR> d:\<DIR/file YOU WANTED DELETED> /r:1 /w:1
No follow-on back slashes.
Hasn’t failed me yet 🙂
