DISKEEPER for Windows NT now Defragments Free Space.

GLENDALE, Calif.--(BUSINESS WIRE)--March 13, 1995--Executive Software has included the defragmentation of free space in its first release candidate of DISKEEPER(R) on-line defragmenter for the Microsoft(R) Windows NT(TM) operating system. The defragmentation of free space (different from file defragmentation) is a major new feature, and a key factor in maintaining peak system performance.

File fragmentation refers to files that are broken up into segments and scattered across a disk. Free space fragmentation refers to free (unallocated) space on a disk that is broken up into segments and scattered across a disk. While file fragmentation causes performance problems when reading files, free space fragmentation causes performance problems when creating and extending files. On crowded disks, free space fragmentation actually inhibits complete file defragmentation. With defragmented free space, files can be SAVED in a more contiguous fashion thereby reducing file fragmentation and performance drains.

"We're aware of the on-going controversy about whether or not the Windows NT operating system fragments," said Jon Knutson, Senior Vice President of Executive Software. "We know that Windows NT DOES fragment, just like any advanced operating system. DISKEEPER's job is to eliminate fragmentation and defragmenting free space is key to getting that job done."

DISKEEPER, the only product available for defragmenting Windows NT, defragments NTFS and FAT files and free space automatically in the background while users are on-line. The product is completely automatic -- all the administrator needs to do is "set it and forget it(TM)" and DISKEEPER eliminates fragmentation from the system. Also added to this release candidate is the option to schedule the program to run, or not run, during specific times, and to select which drives are to be included or excluded from the defragmentation process.

Prior to Windows NT, estimates of the cost of fragmentation on other operating systems have ranged into the the hundreds of millions of dollars annually for Fortune 1000 companies. Unlike Windows NT, some operating systems have sought to hide the gradual performance decline fragmentation causes by limiting the amount of data read into memory at a time--thus maintaining a consistent slowness. With Windows NT ability to read vast amounts of data into memory at a time, DISKEEPER can do its job of eliminating fragmentation and restoring performance lost due to fragmentation.

DISKEEPER supports Service Pack One, hard drives of all sizes including 4-gigabyte and larger, and multiple CPU machines. Platforms supported are Intel x86, Alpha AXP, and MIPS. DISKEEPER will support Windows NT version 3.51 (currently in beta) when Windows NT version 3.51 ships to the public. (Beta versions of the operating system will not be supported.)

DISKEEPER for Windows NT is priced at $149 for Windows NT Workstation and $349 for Windows NT Server. There are no client access charges. The special pre-release discount of 30% will be discontinued as soon as the product is released.
