No matter how powerful your PC is, fragmentation will slow it down—it's just a matter of time. In fact, the harder your system works, the faster fragmentation builds up. Manual, single-pass defragmenters simply can’t keep up—in order to maintain performance; you’d likely spend more time defragmenting than you will using the computer! Diskeeper, the Number One Automatic Defragmenter, simply makes the problems of fragmentation go away forever. Diskeeper 10 Professional Edition provides high-speed automatic defragmentation along with advanced settings and features that allow you to fine-tune its operation. You can set multiple time schedules per volume and choose from advanced CPU-priority settings—or you can take advantage of the intelligent technology built into Diskeeper 10 to find the best settings. Diskeeper 10 Professional Edition can even proactively protect critical system files against fragmentation, thanks to its exclusive FragShield™ technology.
