There are three interfaces to them: graphical, console and native. The first is very useful, because it uses cluster map visualization. Console is good for task scheduler, and native tool – for advanced users and programmers.
UltraDefrag´s design is very ergonomic: no skins, no localization, no animation and so on. It´s a truely small and powerful program!
It can be used on Windows 2000, Windows XP, Windows Server 2003 and Windows Vista. NT 4.0 support is currently unavailable.
Features:
very fast defragmentation, because engine is kernel mode driver and has optimal algorithm.
very small engine written in pure C language.
nice graphical interface – compact and comfortable.
safety, because file moving is realized with special system calls.
simple to use.
generate html reports.
has useful filters.
