FED (ver 2.24c) Abandoned Freeware FED is a programmers Folding Text Editor. It requires DPMI. Folding means the program can visually hide text between a start and end point, which is useful, for example, to hide Loop routines out of the way. Saved changes to the programs configuration are saved in the startup directory in a file "fed.cfg". If you play the built-in Tetris game, high scores are saved in a file "fed.rec".
