Machine utility] To remove a file or files according to some program-automated or semi-automatic manual procedure, especially one designed to reclaim mass storage space or reduce name-space clutter (the original GFR actually moved files to tape). Often generalized to pieces of data below file level. "I used to have his phone number, but I guess I GFRed it." See also prowler, reaper. Compare GC, which discards only provably worthless stuff.
