To obtain the latest version of the program visit please the project's download page.
There are two different types of binaries available for download:
The UltraDefrag Micro Edition is a lightweight version of the program containing only the command line tool and the boot time defragmenter.
You must have a 64-bit version of Windows to run the 64-bit versions of the program. IA-64 version was never tested by the authors. It requires Intel Itanium processor and an appropriate 64-bit edition of Windows.
You must be an administrator to install and run UltraDefrag
You must disable your virus detection software before using UltraDefrag. Any virus scanner running during the defragmentation extremely slows down this process.
Note that UltraDefrag installs to the Windows directory. This is caused by design, because it highly simlifies the program development. Moreover, this is impossible to run the boot time defragmenter without having its files inside the system32 directory.
UltraDefrag can be installed in silent mode by adding the /S key to the installer's command in command prompt. In this case no dialogs will be shown and the program will be installed to the hard drive completely with all the features enabled. The /LANG option allows to select the language pack to be installed. For example, use /LANG=German to install the German language pack.
There is also a silent mode in the ununstaller program. Type in comand prompt %windir%\UltraDefrag\uninstall.exe /S to remove the program from the hard drive automatically without any graphical dialogs.
