The !path and path preference are only used in finding the files
containing IDL functions and procedures. It doesn't have any effect on
searches for other types of files. You can use the CD procedure to set
the current working directory. A more general solution, that limits
typing, is to use the DIALOG_PICKFILE function to display a file
chooser. You can use this function to select a file, then save the
directory path for the default in future calls.
