Under linux yep.

Under windows, well let me put it this way. I've had similar issues as
the original poster has had with other applications. I've had to go so
far as to restart the computer and boot into linux to delete a file
because the moment I'd look at it in explorer it'd lock it to try and
create a thumbnail and wouldn't release the lock.

That's how broken the MS file system is.
