Question
This solution allows Diskeeper to defragment open files safely, whether they are open for read operations or for write operations?
Answer
Diskeeper results do not complete with a fragmentation display showing all the files in one place and all the spaces consolidation into another place? Our primary concern with Diskeeper is the performance of your computer. The disk drives are the primary bottleneck in your computer's performance. Diskeeper restores the disks to top speed by eliminating fragmentation. It is a common misconception that a defragmented disk should look very neat and tidy in the analysis screen, with solid blue bars all the way across the screen (representing fragmentation-free files) and the rest white space (representing consolidated space). Clearly, the speed of the disk, meaning how fast you can access the data on it, is more important than the prettiness of the display or the consolidation of all the free space into one place. Free space consolidation might be important if you have to create one gigantic contiguous file, but it has no effect on performance. So Diskeeper uses algorithms that achieve the highest speed from your drive regardless of the arrangement of the free spaces on the drive and on the screen. Diskeeper does so without wasting time on excessive consolidation of free space. We simply go for the fastest possible file access times and then stop. Even so, you might ask why we don't continue and rearrange the files further to get a neat display? The answer is, “Because it takes computer power to do so.” It would be wrong to consume more of your computer's performance than we give back. So Diskeeper defragments until the disk is in top shape Performance-wise and then stops. Any further work is a waste of your computer resources. Now this might not be a big deal if you like to watch the display as Diskeeper defragments your drive, but it is a very big deal to people who depend on their computers for their work. They need all the performance they can get and can't hold up production while the defragmenter pretties up the disk. This is why Diskeeper is designed to run in the background at the lowest possible priority, giving way to any other program that needs to run. It is also why Diskeeper STOPS defragmenting when maximum performance has been achieved.
