I have a folder tree on my harddisc which I cannot delete during a normal Win2000 session.
When I tried it I got a dialog popup

"Cannot remove folder xxx: Access is denied. The source file may be in use."

I am pretty sure that no program is using it. Even after a reboot it is locked.

So my last hope to get rid of this trash is to delete this directory tree at boot time
when the mysterious program has not already locked the files inside the tree.

How do I do this?
Imagine I have a simple MSDOS batch file with the delete commands inside.
How do I tell Win2000 "perform this file at next reboot" ONCE (!!!) ?
