Martin, Some time ago I posted a similar question. I found Bob Hanlon's suggestion, use the command Input/Get File Path, very useful.

Bob Hanlon "Martin Rommel" <rommel at semitest.com> on 17-04-99 09:35:18 AM Subject: [mg17177] [mg17129] Dialog for selecting a file to be read I often load data files to be processed in Mathematica and it is quite cumbersome that I have to explicitly specify the path and the filename every time. I would rather pick from a list in a dialog window. As far as I know there is no simple way to invoke the operating system's file open dialog from Mathematica. Has anyone come up with a solution? I can imagine that a small external program (maybe linked via mathlink or called with <<"! ) can do the job. Another possibility would be a fancy construct (maybe as a button) using the Mathematica Commands FileNames[], SetDirectory[], etc. If you know of anything related please let me know! Cheers, Martin.
