LHARK - Brother of LHA, faster and tighter.

* * *

[updated 2005-09-24]

Fully compatible with LHA archives. But compression is not fully compatible: LHARK has an additional mode that LHA cannot decompress. LHARK also has a password protection function that LHA lacks.

From the docs:
There are two LHARK modes. The first one (known as LHARK-A) has a set of commands and options that is slightly different from LHA. The second mode (LHARK-B) has a set of commands and options that is compatible with LHA.
Usage: LHARKA4 command archive[.lzh] [-options...] [dir] [@][files...]

ERI and ARI - Excellent compression of multimedia files.

unrated

[added 1999-11-21, updated 2005-09-24]

ERI offers excellent compression stats w/ multimedia files, its specialty (good w/ text files too); average results with executables. Files may be added, extracted or modified within an archive. Two archives can be joined. "Doesn't decompress under WinNT, 2000 and XP. Only under Windows 95 and 98." Available in several languages. ARI is actually an earlier version of ERI, and still useful: good compression, solid archive option, disk spanning, sfx, password encryption, but no multimedia extensions. Some ARI features are no longer available in ERI (e.g., no sfx).

Usage:ERI <command> [-<option>] <ArchiveName>[.ERI] [files...] [-uList] [-x...]
        Example commands:
Convert all BitMaPs to .ERI:           ERI c *.bmp
Add two images to archive:             ERI a archive first.bmp second.bmp
Add files, try to get more compression:ERI a -m archive2 *.exe
Convert .ERI images back to .BMP:      ERI b path\name
Move files from archive, use password: ERI e -d -gdgrbestx archive
Update files in directory, exclude one:ERI e -on archive *.bmp -xGO.*
Delete files, keep same archive date:  ERI d -k archive m*x*.bmp *.bak
Garble two files in archive:           ERI g -gPASSWORD archive name1 name2
Sample files, quering for deleting:    ERI s -dq archive *.*p
Test specified files in archive:       ERI t -s archive \old\*0.* -x\old\.bmb
View all files existing in archive:    ERI v -q -w&x archive

<Commands>
  c: Convert specified .BMPs to .ERIs   n: reName files in archive     
  b: convert Back given.ERIs to .BMPs   o: Optimize files in archive **
  a: Add files to archive               r: Remove paths from filenames
  d: Delete files from archive          s: Sample files to screen with pause
  e: Extract files from archive         t: Test integrity of archive
  f: Freshen files in archive           u: Update files to archive
  g: Garble files in archive            v: Verbosely list contents of archive

X1 - Super tight file archiver can also compress to common archive formats.

unrated

[added 1997, updated 2006-08-21]

X1 compresses text documents significantly better than PKZIP / InfoZip and Ultracompressor, but the compression advantage is less for some other file types (e.g., programs, binaries). While X1 is recognized chiefly for its tight proprietary compression, it also has the ability to compress files to other common archive formats: PKZIP, ARJ, LHA, HA, ZOO, TGZ. Compression, file listing, and extraction are supported, but proprietary options associated with these archivers are not. X1 is available in compilations for DOS, OS/2 and Win9x/NT: all are 32-bit programs, requiring at least an 80386-SX CPU and 4MB RAM. Many command options. Message screens are in English, Dutch, Spanish. Hungarian, Italian, Finnish, German, French.

In X1 for DOS, Win32 LFN support can be set on or off (default=off). Runs under DOS 3.3 or later, including IBM PC DOS 7 and Win9x/NT+.

Usage: X1DOS command[<options>..] <archive> [<data files>..]
<archive>    is the archive name, with a default extension of .ZIP
<data files> are the files to archive, defaulting to all files if none are
             specified.  Wildcards *, ? can be used.

Valid commands are:
A Add files to archive        L List archive contents
C Add comment                 P Add error correcting code (ECC)
D Delete files from archive   R Repair/test archive using ECC
E Extract files from archive  T Test archive cyclic redundance checksum (CRC)
F Freshen files in archive    U Remove error recovery infomation
H Help                        X Extract files with path

Limitations: X1 cannot create self-extracting (SFX) archives. It creates "solid" archives which, if damaged, may offer little hope of repair – attempts to repair may erase files. X1 does offer a data protection option. There may be memory conflicts with some OS & memory manager combinations.

Notes, from a reader: On my P166/32 (DR-DOS 7.03 Lite), with VCPI ("EMM386 DPMI", DPMI turned off at cmdline and NWCACHE loaded), it reboots my machine. If I replace the PMODE/W stub (1.20) to the latest version I can find (1.33), it works without problems. Plus, UPX 2.00 will shrink X1DOS.EXE to less than 200K. However, I think it won't handle newer .ARJ archives (slight change in format?).

X1 has never gone beyond beta testing, and has not been updated in some time.

BOA Constrictor Archiver - Super-tight, option-limited flexible/solid archiver with great compression statistics...

unrated

[added 1999-11-21, updated 2006-03-14]

This tool has the option of creating solid archives (which can't be updated) and offers great compression statistics, but requires significant RAM to achieve best results. Decompression requires like amounts of RAM.

   Usage: boa [command] [options] arcname.boa [files...]

 Commands
   -a         Add files to a a new archive, or an existing one (FLEXIBLE
              only).  This is the default command and may be omitted.
   -x         Extract files with pathnames.
   -e         Extract files without pathnames.
   -v         View archive contents.
   -d         Delete files from archive.  FLEXIBLE archives only.
   -t         Perform integrity testing on files.  This will check the
              archive for CRC errors.  If an error is found, it means that
              the archive is corrupt.  There is currently no way to repair
              a broken archive.

   If you are adding files (-a), then you have additional options.

   -s         Use SOLID archiving.  This option takes advantage of
              redundancy across files.	Compression ratios can be very
              much improved, especially when compressing many similar
              small files.

   -r         Recurse into subdirectories.  This option will make BOA
              also look through directories in the specified paths for
              files to add.

   -p<0,r,s>  Store no paths, recursed paths (see previous option), or
              both specified and recursed paths.

   -m<x>      Use 'x' megabytes of extended memory.  More memory means
              better compression in most cases, but be aware that the
              same amount of memory will be needed on decompresssion.

   -X<file>   Exclude specified file.

   -S	      Include hidden/system files.

32-bit DJGPP program, requires 80386+, DOS Protected Mode Interface (CWSDPMI [included] or other), 2MB+ RAM; default compression requires 8MB RAM. Long file Name (LFN) support under Win9x.

QuickFileCollection (QFC) - Collects multiple files into uncompressed archive.

unrated

[added 1998-12-15, updated 2005-12-09]

Use this tool as a first step toward reducing the sizes of archive files. Individual files can have unused space in them, because their clusters have minimum sizes that are not always filled. QFC works by closing up the dead spaces in and between collected files, giving archivers (Zip, ARJ & others) less to encode and store. Unix tar is similar, but works only on individual files, still leaving some empty space that QFC does not. Requires DOS 4+, 80286 (80386 & Win9x for LFNs). Package includes source (Pascal/ASM).

Note: Some archivers do the same job, in producing "solid" archives.

EXE COMPRESSORS, PACKERS, UNPACKERS

Familiar to most programmers and power users – but if you're obsessed with saving disk space, you might want to experiment with these programs (Note: If you already use disk compression software these utils won't save you much space).


UPX (Ultimate Packer for eXecutables) - Tight and versatile 32-bit DOS and Win32 exe compressor.

* * * * *

[updated 2010-06-24, Status: DOS version maintained 2010]

Maybe the most versatile exe format packer on the scene – and it's free. Distinguished from the other packers listed here by its combination of tight compression and an ability to pack a diverse array of executable formats including: DOS exe, sys, & com; DJGPP2 coff, Watcom le (supporting DOS4G & other extenders); 95/98/ME/NT/2000/XP/CE DLLs, Win32 pe (e.g., Netscape.exe), Linux, RTM32 pe, TMT adam, arm/pe, Playstation. Fast decompression; no memory overhead, and can also list, test, and unpack. Still under development. Free under GNU General Public License.

UPX for the PC is a 32-bit program, requiring 80386+. The DOS version is a DJGPP compilation, and requires a DOS Protected Mode Interface (CWSDPMI or other). The Win32 console version has better LFN support than the DOS version. UPX is also available for Linux (80386+, AMD64 & Power PC) and for Atari.

LZEXE - Compresses many executables into smaller, functional programs.
UNLZEXE - Decompresses EXEs packed by LZEXE.

unrated

[updated 2010-06-24]

LZEXE is an older exe packer, one of the first of its type. Executables with overlays cannot be compressed. Saves a backup of the original exe. Available in the original French-language version and in English translation. LZEXE was widely used but in recent years has been mostly replaced by other programs, based on more efficient compression algorithms.

LZEXE distribution packages also include:
COMTOEXE
Converts COM files to EXE (reverse of EXE2BIN)
INFOEXE
Reports exe file length on disk, length of code, min/max memory requested, & more
UNPACK
Decompresses exes packed by MS EXEPACK

UNLZEXE might now be more useful than LZEXE. It decompresses exes that have been packed by LZEXE 0.91 or the earlier (first version) 0.90, including LZEXE.EXE itself. English-language LZEXE packages include UNLZEXE v0.5 (exe + C source code). The later UNLZEXE v0.8 is available in its own package, with version history in the source code's comments.

CUP386 (CyberWare Universal Unpacker, UCFCUP, CUP) - Unpacks many compressed executables.

unrated

[updated 2005-03-02]

CUP386 is regularly cited as one of the best EXE unpackers around – it was developed primarily for hackers and others with a programming bent. Although CUP386 has many debugging and other power-user options, it is often capable of unpacking many formats in one easy step, and that's why I include it here. CUP386 has been tested with the following formats – but was designed to unpack executables packed with unknown software: PkLite, Diet, LzExe, TinyProg, PgmPak, HackStop, WWPack.

Requires a 386+, functions best when memory managers (e.g., EMM386) are not loaded.

Author: Alex Petroukine / Cyberware, Russia (1997).

1997-07-20: v3.4. Final version, development has ended.

ARCHIVE & PACKER IDENTIFIERS

These programs can identify, but not list contents of archives. For archive content finders and listers, go to the File Identifiers and File Finders: System and Archive sections in File Utils - 3. See in particular GetTyp – identifies packer origin of many compressed executables.


SH Archive Identifier (SHAID, Archid) - Command line archive identifier.

* * * * *

[added ?1997, updated 2000-08-09]

The SH Archive Identifier (executable name is Archid) can identify nearly any archive format in recent use, including many self-extracting archives (those which have an *.exe extension). Recognizes ~170 archives and ~76 executable archives. SHAID returns error levels specific to each archive type and has obvious uses in batch files.
