Defragment Hard Drives
MOVE non-contiguous "fragments" of a file to a single contiguous location.
Full Drive Defragmentation
DirMS can decrease fragmentation in large files by using a partial defragmentation Algorithm and will also Compact files to rid your system of the dreaded interstice problem. The operation of DirMS Similar to Diskeeper, but has some differences, like moving files not just from the bottom of the drive to the top, but actually finding the largest free space that is achievable and moving files to both the front and end of the drive to get the biggest possible free space in which to defragment.
Partially Defragment Suppose you have a huge file that contains several hundred fragments. You might find that some defragmentor programs will not even touch it, since there is no free area large enough to put the contiguous file. That is silly! Un-fragmenting it into a dozen large fragments gives you most of the benefit! If the drive is nearly full, this will be the case for most files. But dirms can partially defragment a file, the best it can under the circumstances, and still provide improvement.
Squish out small gaps between files Other programs actually leave little gaps between files. These do not show up on their interactive displays, so you might not know you even have them! Though you might wonder why a disk that's only 80% full has no visible free areas. you can free download DirMS-CL 3.0.0 now.
