CBS.IFS

IFS for the ZipStream/CryptStream/SecureZipstream compressed/secure file system products. IFS=CBS.IFS

NOTE: Should normally be at the end of config.sys

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.
