Does your screen saver interfere when you defrag your hard disks?
Does 'Drive's content changed: restarting ...' sound familiar?
Does 'Windows cannot defragment this drive because ...' sound familiar?
Defragmenter Lite/Pro is a one-click solution for all these problems and much more.
Did you know that Windows pagefile (swapfile) is the main reason for results after a disk defrag?
The Pro version includes command line capability.
