Reliable and safe operation

The latest version of UltraDefrag is well known to be very reliable. According to our statistics we have gathered throughout the last few years and many millions of UltraDefrag runs, the only thing which can prevent UltraDefrag from doing its job is broken computer hardware, for instance, damaged RAM or CPU. If your computer hardware is working well, on the other hand, UltraDefrag will always do its job perfectly well.

To make that possible we have invested thousands of hours to thouroughly test all the components of UltraDefrag, both manually and using specialized automated tests.

Also UltraDefrag is extremely safe to use. It can never damage your files, because it uses Windows Defragmentation API to move files which is well known to be extremely reliable and safe.
