ZipStream V103b Update Announcement
===================================
ZipStream - the next generation disk compression software
for OS/2.
V1.03b Update Information
=========================
Fixes :
1. Correct problem with moving files between two ZipStream paths.
2. Correct potential problem with reattach logic of zsattach.
3. Correct problem with copy file with EA's in DOS session using
standard OS/2 command processor.
4. Correct problem with zsunpack decompressing files compressed
with the /A option that had negative compression.
5. Correct problem with Workframe V1.1 opening project files.
6. Correct problem with Demon intermittently crashing on startup.
7. Correct problem with Recon, GCP and ZipStream.
Improvements:
1. Improve performance during startup, so that attachments occur earlier
in the boot cycle.
2. Improve install so that the config.sys is not needlessly updated.
3. Search cache is now persistent across boots, resulting in much
improved directory search performance.
4. Search cache now uses a hash bucket hash probed segmented LRU
algorithm for improved performance.
5. I/O priority boost now feed back into requesting threads for improved
performance.
6. Background compression on diskettes is now given priority.
========================================================================
Introducing ZipStream
ZipStream is an exciting new concept in automatic file
compression, that harnesses the power and features of
OS/2 2.X and Warp.
ZipStream is the safe disk compression software
for OS/2 2.1 and Warp.
It is an OS/2 Installable File System
(IFS) that mirrors access to existing OS/2 File
Systems, and simultaneously provides automatic,
transparent file compression and decompression.
Its 32 bit implementation exploits OS/2's pre-emptive
multi-threaded processing capabilities, which allows
for complex processing to be carried out in the most
optimum manner.
ZipStream's transparent background compression
operations and intelligent caching techniques means
there is no noticeable loss in system performance.
ZipStream's Features
* Supports HPFS and FAT File Systems.
Any OS/2 supported file system can be utilised.
* Supports Diskettes.
Diskettes don't have to be specially formatted, just attach and
compression is available.
* Supports LAN File Systems.
Any LAN file system that is mapped as a drive letter can be
used for compression operations. Additionally, there are no
Server overheads, as all compression operations are performed
by the workstation.
* Supports Long File Names.
No restrictions are imposed other that those imposed by OS/2's
native File Systems.
* Supports Extended Attributes.
Full support of Extended attributes and compatible with OS/2's
Workplace Shell.
* Automatic Compression of New Files.
Newly created files or any files copied to the compressed drive
letter are automatically and transparently compressed.
* File Based Compression not Disk Based.
Being file based, you have complete control of what files are
compressed and what are not, that is, uncompressed files can
reside on the compressed drive.
* Ultra High Compression Ratios.
Using state of the art and background compression techniques
yields compression ratios equal to that of popular archiving
programs.
* Native OS/2 32 bit Application.
This isn't a port of a DOS compression application, it's been
built specifically for OS/2 and designed to get the most out of
OS/2.
* Outstanding Performance.
Background compression and 32 bit code gives real pay offs in
performance.
* No Reformatting Required.
Just attach to a driver letter or path and compression is
available.
* No Container Files.
Using existing File systems means reliability and safety.
System Requirements
If you are capable of running OS/2 2.1 or higher, you
can take advantage of ZipStream.
In case you're still unsure, ZipStream has the
following requirements:
* A PC that is supported, and is capable of running
OS/2 2.1 or higher.
* At least 4 MB of RAM, 8 MB recommended, 16
MB perfect.
* At least 10 MB of swap area is recommended.
* A 386 or better CPU, 486 highly recommended,
Pentium outstanding.
