Using Application.GetOpenFilename I can find what file the user would like
to open. But before opening I want to be sure the file isn't already open.
Having the filename I can loop through the set of Application.Workbooks and
check. Problem is the GetOpenFilename returns the full pathname, and
Workbooks is a list of filenames only. So how do I easily extract the
filename from the pathname? I looked around and could not find a function.
If I have to I can loop through the name, find the slash (or colon), and do
a Right. But I would think that there is an easier way.
