ANNOUNCING THE PUBLIC BETA TEST RELEASE OF THE NEW PC ARCHIVER - JAR
ARJ Software is pleased to introduce a new file archiver to the PC world.
It is the program JAR, now available as a public BETA TEST release for
public testing, evaluation, and comment.
JAR is available in a 16 bit executable (JAR.EXE) for DOS and in a 32 bit
executable (JAR32.EXE) for Windows 95 and Windows NT.
The main advantage of JAR/JAR32 is outstanding compression at reasonable
speeds in a wide range of PC environments. JAR will run on a variety of
PCs including a 640K DOS machine (Intel 8088), a 32MB Pentium Windows NT
machine, and a 16MB Pentium OS/2 machine (in a DOS box). For better
compression, JAR takes advantage of the free memory (free EMS/XMS when
running in DOS).
To go along with outstanding compression, JAR provides a full range of
commands and options (ARJ-like) making JAR possibly the most powerful PC
archiver available.
[NOTE: JAR archives are NOT compatible with ARJ archives]
We compared JAR with some of the leading commercial archivers: PKZIP
2.04g, UltraCompressor II Revision 3, RAR 2.00 BETA 3 for Win32. LHA 2.X
and ARJ 2.X are not included. Their compression size numbers are very
similar to those of PKZIP 2.04g.
COMPUTER: Pentium-100, 8 MB memory, no external cache
OPERATING SYSTEM: Windows 95
CONFIG.SYS:
device=c:\win95\himem.sys
dos=high
files=40
devicehigh=c:\dos\power.exe
JAR.CFG:
32MemoryLimit=2048
CheckAvailableMemory=No
FILE SET: The Calgary Corpus (18 files totaling 3,251,493 bytes, popular
file set used to compression rates).

PKZIP 2.04 Default 8s 544,568 (141%)
FILE SET: Microsoft Visual C++ 1.52 (462 files and directories totaling
18,806,153 bytes, mix of executables, text, DLLs, and object files).

JAR32 Default 177s 7,221,727 (100%)

UC2 rev 3 Default 282s 8,556,558 (118%)
PKZIP 2.04 Default 96s 8,945,476 (124%)
In the above tests JAR has been configured to use 2 Mbytes of memory. With
more memory, JAR can compress even better. Here are the results
compressing the MSVC++ file set on a 24 MB PC with JAR configured to use
10 Mbytes of memory.

JAR uses "on the fly" solid compression to achieve its great compression.
Extraction speed is much faster than its compression speed.
JAR provides many state of the art features including:
1) Diskette spanning archives
2) Password option for encryption or user authentication
3) Chapter concept providing for multiple backups to a single archive
4) Options to recover files from damaged archives
5) File selection based upon file name, date-time, and/or attributes
6) Long filename support for Windows 95 and Windows NT
7) Support for handling over 50,000 filenames
8) Option for a byte for byte file compare check during an archive build
You can download the JAR beta test release from:
ftp://ftp.std.com/pub/jar/JAR101BX.EXE - JAR version for world-wide use
ftp://ftp.std.com/pub/jar/JAR101B.EXE - JAR version for USA domestic use
(contains encryption modules)
Both files are ARJ self-extracting ARJ-SECURED archives.
