Did semantics of deleting a file change from Win 2K to Win..

Archived from groups: microsoft.public.windowsxp.general (More info?)

We've got a program at work that has two parts - one part is processing
files, and the other part is delivering files. There are occasions when we
can get a delivery of a file with the same name as an existing file. In that
case, we basically do the following:

request to delete orignal file
move the new file to replace the original file

Under Win 2K, if the file we wanted to delete was being processed (i.e. it
is being used), we'd get an error, and we'd skip that file, and report the
error. The old file was still there.

Under Windows XP (mostly with SP2 - I'm not sure we have any SP1 machines
left) we still get an error that the file is in use, but the file _does_ get
deleted when it is no longer being processed.

Did the semantics of dealing with delete requests change under Windows XP?
If so, is there any way (registry settings, etc.) to make it switch back to
the old behavior?

Thanks.
