- Well I'll admit that I could be wrong but I'm "sure" that file locks
- aren't "physical" and in any case they wouldn't be stored inside a file
- or it would distort the file (you'd have to know where it was and skip
- over it i.e. read past the lock) and that just isn't done.
-
- At worst lock info would be kept in the directory entry but I'm "sure"
- that isn't the case also.
-
- These things should all be implemented logically (not physically) so any
- lock would be released when the power went off (on a network it might take
- a little while until the network noticed that the process who had the lock
- is no longer running) but it can't be permanent.
-
- What is the exact message that you're getting when you try to re-run the
- application ?
