UltraCompressor II detailed information.
========================================
AIP-NL (a company located in The Netherlands) has released a
datacompressing archiver: UltraCompressor II (UC). This archiver uses
completely new archiving and compression technology developed by AIP-NL
with help of the University of Utrecht.
AIP-NL claims UC compresses 10%-50% better than competing software yet
at the same time can update archives up to 10 times faster. UC is "try
before you buy" software, allowing you to verify our claims.
This document contains 3 sections.
[1] UltraCompressor II feature overview.
[2] Benchmarks.
[3] Common Questions and Answers (January 1994).
If you have any questions or remarks please contact AIP-NL:

[1] UltraCompressor II feature overview.
=========================================================================
GENERAL FEATURES
----------------
* BETTER COMPRESSION
On an average 10%, but often above 50%, better compression than
competing software.
* SPEED
Compression is fast and configurable to favour compression speed
or archive size. Extraction is very fast. UC is also very fast
when it UPDATES an archive, even if this archive is large,
stored on a network server or stored on a slow (floppy) disk.
* RELIABILITY
Archives can optionally be protected against damage, allowing
them to recover from most disk-errors without any loss of data.
UC always works 'transaction oriented' allowing recovery from
most crashes without any loss of data. It has optional
double-verification, preventing data loss in case of hardware or
software problems.
* EASY TO USE (INTEGRATED HELP)
UC has integrated help and an, easy to use, integrated
configuration tool. Only a few commands are needed to manage
archives with UC. UC can automatically deal with ARC, ARJ,
LZH, ZIP etc. archives as if they are UC archives.
* FULL SUPPORT OF OS/2 2.X EXTENDED ATTRIBUTES
OS/2 2.x extended attributes (such as icons, WPS long icon
names, WordPerfect 5.2 for OS/2 summary information etc.) can
be kept in an archive. They are managed automatically.
BUSINESS USE
------------
* SCRIPT FILES
A 'script' file can contain a large list of files (e.g. to be
compressed). A script file can also be used as a substitute
for multiple (complex) commands. Script files can be nested,
to allow the construction of 'building blocks'. Script files
can be extremely long (multi-megabyte).
* CAPABLE OF HEAVY DUTY TASKS
There is almost no limit to the amount of files in an archive
or to the amount of files processed in a single command. Where
some other programs get into trouble with more than 10,000
files, UC can easily handle a much larger number of files. Even
a simple PC-XT can (given time) handle this workload.
* ERROR HANDLING AND LOGGING
UC has advanced error handling and logging. This is
especially important when large collections of files are
archived from shared (network) disks. In almost all cases UC
allows you to solve severe problems and enables you to
continue the operation.
* STATE OF THE ART ENCRYPTION
UltraCrypt (a separate AIP-NL product) can protect your data
with heavy duty enhanced-triple-DES (Digital Encryption
Standard) encryption. Faster encryption is included as well.
* STATE OF THE ART AUTHENTICITY VERIFICATION
UltraSeal and UltraSafe, separate AIP-NL products, can help you
protect your data against undetected changes (e.g. virus
infections or data falsifications). They do not use 'security by
obscurity', but they use digital signatures based on Lucas
Exponentiation.
PROGRAMMERS
-----------
* FILE VERSION MANAGEMENT
File version management allows you to recover previous 'states'
of your projects ("... but this worked two weeks ago, what
changed?").
Multiple versions of a file (e.g. the MAY 2 21:33:18 and the
MAY 3 02:17:22 version) can be kept in an archive. UC version
management is very simple to use. Extracting collections of
files from the past is trivial with the 'Dynamic Time Travel'
option.
* VERY FAST UPDATES
UC is very fast in updating large archives while maintaining
superior compression and reliability. No complex commands or
options are needed for this.
* TRIVIAL PATH MANAGEMENT
With UC it is very easy to copy any set of files from anywhere
on disk to anywhere in the archive and vice versa.
BBS SYSOPS
----------
* MULTIMEDIA BANNERS
UC allows you to add multimedia banners (text, graphics, sound
and music) to an archive, or to a collection of archives.
* EASY CONVERSION COMBINED WITH VIRUS SCANNING
UC can convert collections of archives of almost any kind with
just one simple command. If preferred, UC will scan archive
contents for viruses during conversion.
* GET RID OF VIRUSES FOREVER
The industrial strength authenticity verification software (see
'business use') can help you to get rid of viruses forever by
protecting archives against unauthorized changes.
* NEEDS ONLY 32KB FREE MEMORY TO RUN
UC can be used together with other large programs, perfect for
mailers and other (large) programs that need to call UC.

[2] Benchmarks.
=========================================================================
This is a reproducible benchmark made by AIP-NL with the help of 'Dean
Cooper's comparer program, Version 1.02'. It compares UltraCompressor II
with PKZIP 2.04g and ARJ 2.41. Of course, the user can perform the best
benchmarks by comparing the tools in 'real life' situations. The test
has been performed on a 486/33 PC with MS-DOS, QEMM and Norton Cache
(flushed before each test) loaded.

[3] Common Questions and Answers (January 1994)
=========================================================================
What is the price of UltraCompressor II?
UltraCompressor II (tm) single license $43
UltraCrypt + UltraSafe single license $ 7
UltraSeal license $29
Shipping and handling $ 8
25% discount if ordered before April 1994, OR by a sysop.
When will UltraCompressor II be available?
A 100% functional package is available NOW.
Who is UltraCompressor II intended for?
Everyone who wants the most cost effective data communication
and storage possible. Programmers who want rapid backups and
easy to use version management. Sysops who appreciate multimedia
banners and REAL authenticity verification.
Is there any difference between the "trial" and an official version?
When you buy UltraCompressor II it contains a serial number, and
comes with a printed manual. Other than these, there are
absolutely no differences in the software, or in the contents of
the manual.
Which operating systems does UltraCompressor II support?
UltraCompressor II detects and utilizes DR-DOS, PC DOS, MS-DOS,
the Microsoft Windows family, DesqView and OS/2.
Is on-line documentation available?
Yes, UltraCompressor II has an integrated, easy to use, HELP
tool.
Is a configuration tool available?
Yes, an easy to use configuration tool is built into
UltraCompressor II.
Does UltraCompressor II support ZIP, ARJ, ARC etc. archives?
Yes, UltraCompressor II supports (extendable) transparent
support for 9 archive formats.
Does UltraCompressor II support 3rd party tools?
Yes, a special interface, the UC2-3PI (UltraCompressor II 3rd
party interface), is integrated in UC. For more information
please contact us.
Does UltraCompressor II support multiple-volume archives?
No, this is scheduled for the next version of UltraCompressor II.
Please contact us if you want to become a beta tester.
Can UltraCompressor II create self extracting archives?
No, the special compression architecture, which makes UC
compression superior to others, does not allow us to create a
small 'SFX' module.
Does UltraCompressor II utilize system resources?
Yes, UC utilizes operating system, EMS, XMS, network and
microprocessor specific features whenever available. UC,
of course, does this in a conservative way.
How much memory does UltraCompressor II need?
462 kilobytes when no EMS is available, 400 kilobytes when EMS
is available. Please note that UltraStealth allows you to run UC if
only 32 kilobytes of free memory is available.
Can "multimedia banners" be disabled?
Yes, a single toggle in the built in configuration tool is
sufficient to disable multimedia banners.
How much damage can a "damage protected" archive recover from?
A damage protected archive can always recover 100% from a single
bad sector. For "large" archives about 1% of damage can be fixed
completely (e.g. in a 1Mb archive 20 bad sectors can be
restored). If complete recovery is not achievable, UC will still
recover as much as possible from your data. Please note that
damage protection is optimized for bad sectors, it has no disk
repair facilities like e.g. Norton Disk Doctor.
