Diskeeper 7.0 Build 413 Workstation/Server Edition Diskeeper eliminates No.1 performance problem, fragmentation of the Hard Disk. Built-in defragmenters are manual-only and require full administrator privileges to operate. They are slow, labor intensive and use too much system resources to keep up with the performance demands of today's computing needs. Ultimately they don’t get used. Running Diskeeper is like hiring an expert to constantly monitor and maintain your system’s maximum performance. Diskeeper is the fastest defrag engine ever built. National Software Testing Lab (NSTL) proven 300-500% faster and far more thorough than “built-in” defragmenters. Features include the exclusive “Set It and Forget It” functionality with Smart Scheduling, that, once set, runs invisibly in the background - fully automatic. The “Frag Guard” feature helps prevent fragmentation in your most critical NT/2000/XP system files. Additional features include boot time defrag, priority settings as well as the ability to defrag multiple disks automatically and simultaneously while system is in use.
