Determining who has an Excel file open

[Matthew Pfluger]

I maintain an add-in on my company's shared drive, and I want to determine
who has the file open at any given time. I can already determine if the file
is open, but how can I obtain a list of users who are accessing the file?

Thanks,
Matthew Pfluger

This is from a post last year (which I just stumbled across...):

the approach is to try to open the file with exclusive access using low
level fileio.
