Most Windows users are familiar with the Disk Defragmenter utility -- or, at least, they should be. Defragmenting your hard drive can improve your computer's performance by making sure that files are all stored in one spot on the disk. There are plenty of alternatives to the built-in Windows defragmenter, including UltraDefrag (32-bit). This program comes with a defragmenter and other optimization tools that can ensure that your computer is performing as it should.
UltraDefrag has a simple interface that will look familiar to anyone who's used this kind of software before. We clicked the Analyze button, and the program quickly performed an analysis and displayed the results in a cluster map. We then clicked the Defragment button and UltraDefrag did its thing. We decided to check its results by running the native Windows utility; oddly, that program reported that we needed to defrag our disk, even though we just had. We returned to UltraDefrag and ran its Optimization feature. This took quite some time, but when we were done, the Windows utility confirmed that our disk no longer required defragmenting; UltraDefrag had done a thorough job. The program has a fairly detailed online Help file, but it's definitely geared toward people who already have some familiarity with the concepts of defragmenting and optimizing your hard drive. Overall, we found UltraDefrag to be a nice alternative to the built-in Windows Disk Defragmenter, and we recommend it.
UltraDefrag (32-bit) installs and uninstalls without issues.
UltraDefrag is an open source defragmentation tool. Its engine is very fast, because it is created as kernel-mode driver. They are three interfaces to them graphical, console, and native. UltraDefrag reduces the file fragmentation, thus it makes disk operations faster. Also the program can optimize a whole disk placing all the files to the fastest part of the disk - to its beginning.
