GS Extra to type in PATH from finder?

[tws <adoyson@nccn.net>]

Is there any program available for the GS that will allow you to type in
a PATHNAME to see the contents of a folder or run a file?

Hard Drive directory:

MAIN/
MAIN/Applications/
MAIN/applications/telecommunications
MAIN/applications/telecommunications/Spectrum


Then, instead of clicking on each consecutive folder, you could just
type in /MAIN/applications/telecommunications/Spectrum

and then the Finder opens a window for that folder.  You don't have the
THREE extra folders open (the ones called :

MAIN/
MAIN/Applications/
MAIN/applications/telecommunications)

When these folders are open, you don't need them to be and they are
cluttering up the desktop.

Is there such a program?
