I can't believe that RSI's techsupport did not know this or maybe
it's me and I did not get your point.

Just use
dir_entries = findfile('*.*',count=filecount) ; for Windoze

and you get a string array dir_entries with all file and directory
names in the current directory. Keyword count returns the number
of found files.

However, under UNIX the metachars are interpreted different.
I would simply stick with spawning a ls command in this case.

The Windoze common dialog box has another annoying quirk: it's
button label is fixed to "Open". This is confusing in
applications where you want to choose a filename for saving instead
of opening a file.
IDL would better introduce a keyword for OS_PICKFILE to set the
respective button label from outside.

Before constructing your own pickfile widget, I would consult the
searchable list of IDL routines at http://www.lpl.arizona.edu/idl.html
It contains the routines from all publicly available IDL libraries.
Perhaps someone else has already done your work.
