This defrag beats them all. It analyzes, defrags and compacts. Fast. Thorough. It has filters to exclude desired folders. System Volume Information, temp, and recycler are defaulted filters. I added Sandboxie to the filters. When I check the report it lists these files with a black background with white print. Previous reviewer wondered why it didn't defrag all the files listed. Possibly the filtered strings are the answer. This is an excellent program.

This defragger not only does a great job, but it comes in a portable version (included with the download) as well. Seems to work very well on my Vista platform. Thanks and keep up the great work !

UltraDefrag 1.2.1 looks very good; the GUI is eye catching and very colorful. Unfortunately, the performance of UltraDefrag 1.2.1 leaves much to be desired! I tested UltraDefrag on my 200GB HDD with about 50% of free space; UltraDefrag found 700+ fragmented files; it defragged 300+ files leaving 400+ files still fragmented! I'm not referring to System files or other HDD files that can't be defragged; the un-defragged files were music files, text files, etc; just ordinary files. UltraDefrag does provide the user with a very nice listing of the un-defragged files, I would just like to know why the files weren't defragmented! I'll pass on this HDD defragger!
