ELI 5750
From Just Solve the File Format Problem
ELI 5750 is the apparent name of a compressed archive utility for DOS, and its associated .ELI file format.
No documentation has been found. The software's banner message reads as follows:
ELI 5750 Demo Version Collection create/update/extract utility Adar 5751. Copyright (c) 5750 by Jule Revsin. All Rights Reserved. Type ELI -? for help.
It supports two compression schemes, which it names "Crowding" and "Twisting".
Identification
ELI files apparently start with ASCII "Ora
" (which includes a trailing space).
