This can't be done with anything built into IDL, since
Dialog_Pickfile does not support multiple directory
selection. (It does support multiple file selection,
so I suppose it *might* work in UNIX, but I can't test
it here.) Such a compound widget would be fairly easy
to build, I should think. 

Getting the information back to the calling program is
also easy. See the "Writing Modal Widget Dialogs" chapter
of my book. :-) (Or, if you are one of the three or four
people still without a book, see a program like GetImage
on my web page for an example of how it is done.)

Cheers,

David
