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.

OPTIONS:  U - The EXE Packer has the ability to uncompress the .EXE
              file back into its original form.
          E - The EXE Packer has the ability to encrypt the .EXE file
          P - The EXE Packer has the ability to add error protection
              data so it can inform the user if the file has been
              changed in any way (ie: infected by a virus)

                  ***  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:

### 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)
ftp.simtel.net    /pub/simtelnet/msdos/arcers (400+ Anon Users Allowed)
ftp.coast.net     /SimTel/msdos/archiver  (400+ 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.

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.

        The information above may not be 100% accurate so if anyone
notices any errors or finds something I left out, please let me know.


** NOTE ** - I will be upgrading my RAM from 8 megabytes to 20 megs!
             So next month's ACT will have much more accurate time
             results for ACB, RAR, and all the archivers that need
             large amounts of RAM.

ACB 1.23a - This new version of ACB requires at least 16 megabytes of
            RAM.  You can run ACB in a Windows 3.1/95 dos box using
            disk swapping if you don't have 16 megs RAM but I would
            not recommend it.  I had to abort the testing for 669
            and CalgaryCorpus tests as they would have taken over
            24 hours of non-stop compressing with 100% CPU usage.
            This is due to the fact that I only have 8 megs RAM and
            Win95 takes up most of that for the OS.  Almost all of
            the RAM ACB needs is swap space.

RAR'95 2.0 beta - The Windows95 version of RAR 2.0 beta is not yet
                  publicly available so you will have to wait for its
                  official release.  I can say the interface is very
                  nice and easy to use.  A major feature that is
                  available in the Win95, OS/2 and UNIX versions is
                  the ability to use larger dictionary sizes.  A
                  dictionary size of 64k,128k,256k,512k or 1024k can
                  be specified and many times results in better
                  compression.  The larger the dictionary size, the
                  slower RAR performs and if you don't have lots of
                  RAM, it can be very slow on large files if Win95
                  starts to use the swap file.

XPACK 1.30 - I have been in contact with the author of XPACK and that
             nasty timing bug is now fixed in this latest release.
             A third compression method has been added but execution
             is much slower.  You can also now uncompress .COM and
             .SYS files that were xpacked.  Compression in general has
             improved for all methods.
