LGLZ is an executable compression utility for DOS, developed by George Lyapko. It compresses EXE and COM formats.
The software has a -x
option, to decompress a compressed file.

[edit] Format details
LGLZ has some options that may significantly affect the compressed file, including:
-0 - compression method 0 -1 - compression method 1 -f - Use the fast self-extracting module -u - Create a compressed file, which is unextractable (by this program)
The documentation mentions DIET as an inspiration. LGLZ's compressed files do seem to have some similarity to DIET's.
[edit] Identification
(Based on v1.04a-e.)
EXE: Compressed EXE files are observed to have ASCII "LGL
" at offset 28.
COM: The 15 bytes starting at offset 3 always seem to be 3b fc 72 19 b4 09 ba 12 01 cd 21 b4 4c cd 21
. Following that, at offset 18, is the ASCII string "Memory fault$
".
