Disk Compression Facility for OS/2 (Version 1.1b/Version 1 Update)
Increase Your Disk Capacity without affecting Your OS/2, Windows or
DOS applications! Complete HPFS Support including all FAT-based
Removable Media
Proportional Software's latest DCF/2 "on-the-fly" disk
compression for OS/2 is a fast, reliable software solution which
can increase your disk space right NOW -- without changing your
existing system organization or disk format. The DCF/2 works
with all logical OS/2 2.0 and 2.1 disk devices, including
FAT-based removable media and network disks.
The DCF/2 reduces your OS/2 and program space requirements so
that everyone can enjoy the power of OS/2!
Don't Settle for Outdated DOS Technology:
Unlike products ported from DOS, the DCF/2 uses a modular,
multi-threaded architecture designed to grow with your OS/2
desktop. Traditional DOS products bypass the operating system;
the DCF/2 exploits the POWER of OS/2 to its fullest.
More Than Just Simple Compression
The DCF/2 builds on OS/2 and its underlying installable file
system (IFS) architecture. Installable File Systems, like the
High Performance File System (HPFS), offer OS/2 users access to
powerful disk hardware platforms without demanding hardware
dependence. The DCF/2 continues that philosophy by layering
into the kernel-IFS architecture so that OS/2 uses the DCF/2
transparently & logically without respect to host drive media
type.
The DCF/2 creates virtual disk units (VDUs), providing OS/2 with
system-wide access to compressed volumes totally transparently.
A DCF/2 VDU appears to OS/2 as a "real" disk. This means that
you can use all of the OS/2, Windows, or DOS tools and
applications you already have without rethinking the way you
work!
Exploit the Power of the HPFS:
The DCF/2 compressed volumes are HPFS-based. This means that
ALL of your programs can access ALL of your files! Even more
significantly, the HPFS-based VDUs are kept logically contiguous
by the file system itself, reducing the need to periodically
defragment your disk. File data are stored at sector
granularity (512 bytes) instead of by archaic FAT clustering.
This provides you with at least 20% additional data storage --
even before the DCF/2 compression!
Use Any of Your Disk Media:
Your VDU can reside on any OS/2 disk type, including FAT,
network, or other DASD. Removable-media such as floppy
diskettes, optical-writables, and Bernoullitm-like technologies
are fully supported.
