The UltraDefrag Micro Edition is a special package for advanced users who prefers extreme stability and power. This edition is a little bit faster, much stable (its driver contains just most important parts). It has only console interface to speed up defragmentation process. Boot-time feature is available too. The Micro Edition saves reports in plain text format. You can find them in x:\fraglist.txt file (x = drive letter).
Note that console interface is very powerful, it has a full set of commands to perform any disk defragmentation job. To show full list of UltraDefrag related commands type ud-help.
