External for running one instance on windows

[Jim Bufalini]

Correct. Creating files and depending on your program to delete them, on
exit, is a recipe for disaster. This only works with file locking, and even
then, it depends on the network OS to release the lock, when the program
exits (doesn't always happen, depending on the network, and a combination of
other factors). -Jim

This would only work if the program deletes that file before it closes -
right?

But, if the program crashes or the power gets cut off and the file is
not deleted, then the next time the program opens, the file will still
be there, and the program will think it is already running, when it
isn't.

There is another way to check if an instance is running
that will work on all OS. When you start the program you
create a file if it is not already there. If it is there
then you close the program.

I hope this helps.
