ZipStream Secure v. 2.0 (demo, 17/7/2000, Carbon Based Software) |
Readme/What's new |
What is ZipStream ?
ZipStream is an exciting new concept in automatic file compression, that harnesses the power and features of OS/2 2.1, 2.11, Warp Version 3 and higher.
ZipStream is an OS/2 Installable File System (IFS) that mirrors access to existing OS/2 File Systems simultaneously providing automatic transparent file compression and decompression.
The ZipStream Concept
To further understand the ZipStream concept, consider the following scenario.
You have an existing OS/2 system with the file letter.doc in the root directory of the C: drive.
ZipStream is installed and drive C: is mirrored as compressed drive X:. This is achieved using the ZSAttach utility as follows:
zsattach x: c:\
Access to all files on drive C: is now possible simultaneously via drive X:. i.e. The commands
type C:\letter.doc
and
type X:\letter.doc
will achieve the same results.
Now letter.doc is compressed with the ZipStream file compression utility ZSPack as follows:
zspack c:\letter.doc
Typically, a text file like letter.doc will be reduced in size by at least 50 percent. Compression ratios of around 80 percent can generally be expected on large text files.
Access via C:\letter.doc will reveal its compressed contents, but access via X:\letter.doc will allow access as if the file is uncompressed. That is, ZipStream recognises that the file is compressed and transparently decompresses it.
Transparent Background Compression
Any new files copied to a ZipStream compressed drive will be automatically and transparently compressed in the background. |

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.
