 Yes, but the problem here is who is deciding this? You cannot know
 how your users have their data stored.

 Also, as regards the .CEL/CDF file thing -- it will probably be a
 good idea to follow the dChip model (and one used by lots of others),
 and have yet another widget that sets up 
  1) where the CEL files are
  2) where the CDF file is
  3) where output will be saved (if done automatically)

 Then, the fileBrowser widget is activated by a Browse button at those
 locations in your applications pop up widget.

 It is reasonably important not to try to do too many things with one
 tool (this leads to non-modular code and can lock you in to things
 that you never intended).
