If you don't care about who has the file open, you can modify Ivan's code or
just start out using this simple code (the guts of which is identical to the
approach used by Ivan).

Thanks for any help.
I have a macro (Excel 2000) in a workbook that copies and pastes some tabs
into the workbook it opens. But sometimes the files that it opens are
already
open by another user. In that case, there is an error message and some
other
stuff can happen that messes up the program. I would like to stop this, is
there any properties or code that I can do to tell if a file is already
open?
I thought of using an On Error stuff, but is there another way?
Thanks again.
