vt. [ITS] From 'Grim File Reaper', an ITS and Lisp 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.
