Have you ever met the annoying dialog box stating that the file you are trying to delete can’t be deleted – stating that it is in use (even though you KNOW this NOT to be true?)..  Sure you have, especially running Vista (strangely enough I seem to see this issue more often on my Vista box than on Win2003/xp) ..   Well anyhow, there are ways to deal with that (not guaranteed, but quite often it works).. http://ccollomb.free.fr/unlocker/ is a small freeware utility that will assist in resolving this, it can quite often delete a file that states its locked. UPDATE Nov 2009; Also check https://readmydamnblog.com/?p=1045 for an alternate utility in a 64bit version (Lockhunter)
