LHSFX - Self Extracting Archive Creator
By Mike Kennedy ©1991
-----------------------------------------
Version 1.1 20/04/91
Have you ever wanted to create a self-extracting archive? They make
life much easier for software developers and provide protection from
bogus copies of your precious work. LHSFX allows you to create your
own self-extracting archives... with data compression better than
ZIP and LHARC.
LHSFX uses compression an improved version of the LHARC compression
algorithm which allows an speed increase of over 40% and 3% better
compression. Decompression is almost incomparable... Apples to
Oranges... Usually around 500% faster. On small files the
increased compression may not be apparent because the extraction
header is a little over 2k long.
Here are some compression comparisons between LHSFX & LHARC...

LHSFX - 72312 01:01 00:08
LHARC - 78962 01:48 00:38

----------------------------------
Final Compress Extract

LHSFX - 12796 00:15 00:02
LHARC - 13391 00:36 00:09
----------------------------------
LHSFX is easy to use. Once you've started it up, enter the name of
the archive you want to create. It will check to see if it exists
and if it does, it will ask you if you'd like to overwrite it.
Then begin entering names of files you want compressed. If you want
a text file displayed while the archive is extracting, type in it's
name and press D for Display at the prompt. Otherwise, press F for
File. For files, enter the extract path, in other words the name
of the file when it is decrunched, including names of subdirectories.
Here's an example....
--------------------------------------------------------------------------
DESTINATION > ram:testfile.exe
ORIGINAL > df0:info.txt
»> df0:info.txt (1234 bytes)
Compressing... Please Wait.
Crunched 1234 bytes to 374 bytes.
[F]ile or [D]isplay : D
File Added to Archive.
ORIGINAL > df0:program
»> df0:program (4321 bytes)
Compressing... Please Wait.
Crunched 4321 bytes to 1342 bytes.
[F]ile or [D]isplay : F
Extract Path > myprogram/program
File Added To Archive.
ORIGINAL >
-------------------------------------------------------------------------
To close off and finish an archive just press return at an empty
ORIGINAL prompt. LHSFX will then complete and close your archive.
It is now a fully self-contained, self-extracting archive. To
extract the above archive, all you'd type 'testfile.exe' at the CLI
prompt.
