LZEXE is an executable compression utility, developed by Fabrice Bellard. It compresses DOS .EXE files.
Contents |
Identification
LZEXE-compressed files normally have ASCII "LZ09" or "LZ91" at offset 28.
As with most compressed executable formats, more-robust identification is possible, by looking for the characteristic decompression code.
Software
Compression software
- LZEXE
- "LZEXE v1.00a" by IS2 France Diffusion. Seems to be functionally identical to LZEXE 0.91.
Static decompression software
- UNLZEXE - A widely-distributed open source utility that does static decompression of LZEXE-compressed executables. Originally by Mitugu Kurizono (Kou). Versions "0.6" and above include patches by other authors, and might be unofficial.
- mz-explode
- Deark (with
-m lzexeoption) - Rizzle
Dynamic decompression software
- UNP - An example of a dynamic decompression utility for DOS
Protectors
(utilities that modify a compressed file to make it more difficult to identify and/or decompress)
- ANTI-UNLZEXE
- LZALT v0.03 by Codon Software
- LZEALT v1.04 by De Trans Software
Links
- LZEXE home page
- Reversing LZ91 from Commander Keen (This is reportedly[2] about LZEXE.)
