A.C.T. is now on the World Wide Web (WWW)!  It can be accessed at:
                 http://www.mi.net/act/act.html
This is the best way to view A.C.T. since it is in a graphical format
and most authors have a link to their e-mail address.  There are also
links to FTP sites to download most of the archivers.  Finally, there
is a link to my e-mail address to send me any comments or suggestions.
#######################################################################

The following is a test I did on several archivers to compare their
performance against others.

For the following tests with single file types, I used a 486DX4-75 with
8 megabytes of RAM.  No disk CACHE was used at all!  For the timing,
Ultra Precision Command Timer v1.6 by Erik de Neve was used.  The
operating system used was DOS 6.22.  I compressed the tested files from
my hard drive to a 2 megabyte RAM drive.

EXE Pack File Test     -     Uncompressed Size 341,444 bytes

The EXE Pack test compares programs that compress .EXE files and still
allows them to execute.  The .EXE file used in this test is GWS.EXE
found in The Graphic Workshop v7.0e by Alchemy Mindworks Inc.  The
UNCOMP. TIME data shows the amount of time it takes to uncompress
and run the executable file.  This time was calculated using a utility
called BENCH 0.01beta written by Michal Weis (weis@elf.stuba.sk).
The results for ACB, RAR and PKZIP are listed only to show how normal
archivers compression ratios compare with EXE Packers.

                  ***  PART 2 - MULTIPLE FILE TESTS  ***


I compressed a directory containing 21 files totalling 3,255,838 bytes
on my hard drive to a 2 megabyte RAM drive.  This directory contained
the original files from the Calgary Corpus archive (CALGARYCORPUS.ZIP)
which contains text, binary and graphical files.  I used a 486DX4-75
with 8 megabytes of RAM to do this test.  No disk CACHE was used at
all!  For the timing, Ultra Precision Command Timer v1.6 by Erik
de Neve was used.  The operating system used was DOS 6.22.

Here are my results:

In the second multiple-file test, I took 130 small TEXT files totalling
1,121,394 bytes and compressed them using the same method as before.

### LOCATING ARCHIVERS FOR DOWNLOAD ###

         The easiest way to download the archivers listed in A.C.T. is
to use the WWW version of A.C.T.  If you cannot access the WWW then most
of the archivers can be found on the following four FTP sites.  Try them
in this order:

ftp.elf.stuba.sk  /pub/pc/pack     (6 Anonymous Users 13:00-06:00 GMT)
ftp.kiae.su       /msdos/arcers    (20 Anonymous Users Allowed)
oak.oakland.edu   /SimTel/msdos/archiver  (300 Anonymous Users Allowed)
garbo.uwasa.fi    /pc/arcers       (100 Anonymous Users Allowed)

------------------------------------------------------------------------

         As you may or may not have noticed, I have been releasing these
test results about once a month.  I have decided to release the results
on the first day of each month and name these tests A.C.T.

* Please note that the best overall selection is based entirely on the
archiver's compression/speed ratio.  It is NOT based on the reliability,
price, technical support or the options available in the archiver.

        I have decided to add an Options List which shows what archivers
support certain major options.  If you think I should add another
category to the list or you see an error, please let me know.  If there
is an error, please tell me what switch will activate the command that
I missed.

---------------------------- OPTIONS LIST ------------------------------

MULTI-DISK SPAN = Ability to span an archive over two or more disks
AUTH. VERI.  =  Authentication Verification (Security Envelope)
DATA PROTECT.  =  Data Protection Encoding (Stores Error Recovery Info)
ENCRYPT  =  Ability to encrypt files in archive with password (Garble)
SFX  =  Ability to create Self-Extracting Archives (.EXE)
GUI = Graphical or Text Shell to manage archiver functions and select
      files for compression/decompression
MANAGE OTHER ARCERS = Ability to manipulate, use and convert archives in
                      formats other than its own

* - UC2 comes with a utility (SAS.EXE) to SPLIT archives into chunks
    and then rebuild them after.  This is not nearly as nice as
    multi-disk spanning.
  - INFO-ZIP comes with a utility called ZIPSPLIT which does the same
    thing as UC2's SAS utility.

% - UC2 uses shared dictionaries between file collections to utilize
    similarities between files.

notices any errors or finds something I left out, please let me know.


ACB 1.13b - This version is using a new format that is not compatible
            with previous versions of ACB. (Big Surprise)
            ACB's compression seems to be getting better and better
            with every release.  Several small bugs fixed.
            To run ACB, you still need at least a 486 and 7.6 megabytes
            of FREE RAM.  The author of ACB now has an e-mail address.

ARJ 2.42c BETA - Added limited multi-volume ARJ-SFX features.  Several
                 switches added and several bugs fixed.  Hopefully a
                 full release will be ready soon since the last
                 official release was in July of 1993.

RAR 1.55 - Slight speed performance increase.  Speed increase in
           'skip', 'update', and 'delete' operations in SOLID mode.
           Some incompatability problems on network drives has been
           fixed.  Several bug fixes with SFX module.
