WHY_ARJ.DOC January 1992
This document describes the benefits of ARJ. ARJ is now the trend
setter in archivers with other archivers following suit.
You can find reviews of ARJ in the following magazine articles:
Computer Personlich, June 12, 1991, Leader of the Pack, Bernd
Wiebelt and Matthias Fichtner. In this German magazine, ARJ 2.0 was
named Test Sieger (Test Winner) over six other archivers including
PKZIP and LHA. Compression, speed, documentation, and features were
compared.
PC Sources, July 1991, Forum, Barry Brenesal, "A new challenger, ARJ
2.0, not only offers the speed of PKZIP, but also has the best
compression rate of the bunch."
Computer Shopper, September 1991, Shells, Bells, and Files:
Compressors for All Cases, Craig Menefee. "ARJ ... is extremely fast
and produces excellent compression; it ... has a rich set of options.
... This is a mature technology, and any of these programs will do a
fine and reliable job."
PC Magazine, October 15, 1991, Squeeze Play, Barry Simon. "Jung has
combined that foundation with academic research to produce an
impressive product. ... If your main criterion is compressed size,
ARJ will be one of your two main contenders, along with LHA."
SHAREWARE Magazine, Nov-Dec 1991, Fall Releases, Joseph Speaks. "Don't
tell the creators of ARJ that PKZIP is the standard for data
compression. They probably already know. But that hasn't stopped
them from creating a data compression utility that makes everyone -
even the folks at PKWare - sit up and take notice. ... but compression
statistics don't tell the whole story. The case for using ARJ is
strengthened by new features it debuts."
BOARDWATCH Magazine, December 1991, ARCHIVE/COMPRESSION UTILITIES,
"This year's analysis rendered a surprise winner. Robert K. Jung's
ARJ Version 2.22 is a relatively new compression utility that offers
surprising performance. The program emerged on the scene within the
past year and the 2.22 version was released in October 1991. It rated
number one on .EXE and database files and number two behind LHarc
Version 2.13 in our directory of 221 short text files."
ARJ FEATURES:
1) ARJ provides excellent size compression compared to the other
products currently available on the PC.
ARJ is particularly strong compressing databases, uncompressed
graphics files, and large documents. One user reported that in
compressing a 9.0 megabyte database, ARJ produced a compressed
file of size 0.8 megabytes.
2) Of the leading archivers, only ARJ provides the capability of
archiving files to multiple volume archives. In other words, ARJ
can archive files directly to diskettes no matter how large or how
numerous the input files are and without requiring EXTRA disk
space.
This feature makes ARJ (DEARJ) especially suitable for
distributing large software packages without the concerns about
fitting entire files on one diskette. ARJ will automatically
split files when necessary and will reassemble them upon
extraction without using any extra disk space.
This multiple volume feature of ARJ makes it suitable as a "poor
man's" backup utility. ARJ saves pathname information, file
date-time stamps, and file attributes in the archive volumes. ARJ
can also create an index file with information about the contents
of each volume. Files contained entirely within one volume are
easily extracted using just the one volume.
3) The myriad number of ARJ commands and options allow the user
outstanding flexibility in archiver usage. No other leading PC
archiver allows you that flexibility.
4) ARJ provides the facility to store EMPTY directories within its
archives. This makes it easier to do FULL backups and also to
distribute software products that come with EMPTY directories.
5) Both ARJ self-extracting modules provide default pathname support.
That means that you can build self-extracting archives of software
directories containing sub-directories. The end user of the
self-extracting archive does not have to type any command line
options to restore the full directory structure of the software.
This greatly simplifies software distribution.
6) The ARJ archive data structure with its header structure and 32
bit CRC provide excellent archive stability and recovery
capabilities. In addition, ARJ is the only archiver that allows
you to test an archive during an archive process. With other
archivers, you may have already deleted the input files with a
"move" command before you could test the built archive. In
addition, the test feature allows one to select an actual byte for
byte file compare with the original input files.
7) ARJ provides an optional security envelope facility to "lock" ARJ
archives. A "locked" ARJ archive cannot be modified by ARJ. This
provides some level of assurance to the user receiving a "locked"
ARJ archive that the contents of the archive have not been
tampered with. Data integrity checks contribute to the security
of the ARJ "lock".
8) ARJ has MS-DOS 3.x international language support. This makes ARJ
more convenient to use with international alphabets.
9) You will also receive strong technical support from a software
author with many years of experience in software technical
support. The past year of ARJ has demonstrated that ARJ has
improved to meet customer needs.
