UltraDefrag manages file fragmentation on to improve file access time and overall system speed of magnetic (non-SSD) drives. The program includes quick and full defragmentation modes for frequent or occasional (usually monthly) optimization on NTFS, FAT and exFAT-formatted drives. The program is optimized for efficiency and speed versus other available tools and can be paused mid-defrag. See FAQ for usage suggestions.
Supports over 40 world languages and includes a command-line version.
Alternatively, UltraDefrag Portable switches automatically between the 32/64-bit versions and cleans up the fragmentation details left behind on drives.

Ultra Defrag looks good and works fast . I downloaded it just after reading a review at http://www.techsupportalert.com/best-free-disk-de-fragmenter.htm . Just can't wait to see how it works when compared to all other defragmenters I have tried in the past.
PS - Can anyone help me how to enable Boot Time Defragmentation provided I use the portable version.

Because of the different strategies of most defrag apps you can do more false then right:
if you're using Vista/7/8 use the build-in defragmenter on a regular basis,
if you use XP my favourite is DiskDefrag on a regular basis,
if you defragment your hard disk, please use only one app for it.
I'm not a 'fanboy' of Auslogics DiskDefrag or any of their other products.

misan, that sound like an incredibly fanboyish thing to say if all you've got is anecdotal evidence, how about sharing with us these benchmarks you've done to back up this statement?

IMHO: This is the worsest defrag application. I compared and tested it with many other apps. Auslogics DiskDefrag is the best.

My defrag program of choice. I don't know if it's faster or better than other programs here on the site, but I like the open source and system-optimized binaries.

Does UltraDefrag support relative path in the log_file_path = "" switch? Like log_file_path = "..\Log", so it could store the logs inside a folder where the application .exe is.

Avi-aryan: on the Boot Time Defrag, it's unfortunately still only available for the installed version.
