Is there a windows API call which will tell me which process has a file open?

George,

As far as I know there's no simple API call to do this. If you want a
utility that will do it, have a look at the excellent Process Explorer
tool at www.sysinternals.com

It can't be that straightforward either when that article contains a
warning like this:

"This software uses a few undocumented functions (ntdll.dll), peeks
around in your systems internals. Use at your own risk! It works for
me".

Which are the same internal API's used by sysinternals Process Explorer :-)
