This is an upgrading utility similar to DIFF in UNIX but it works with
BINARY files, too. It is a new concept in such programs, from Japan,
as most such programs only work with ASCII source files. Free program.
Suppose you had a file ORIGINAL.EXE and you have revised it up to
REVISED.EXE. You don't want to distrube the entire REVISED.EXE (which
might be very long) so here is what you can try:
LDIFF c UP.DOC ORIGINAL.EXE REVISED.EXE
REN REVISED.EXE TEMP.EXE
LDIFF x UP.LZD ORIGINAL.EXE
You see a message: Old File(ORIGINAL.EXE) is good SIZE & CRC, Creating
REVISED.EXE from ORIGINAL.EXE with UP.LZD CONGRATULATION!! Name of new
file is then C:\REVISED.EXE.
You only have to distribute the UP.LZD file and ask people to use
LDIFF.EXE to get the final LDIFF.EXE. the final ldiff.exe.
