JkDefrag is a low-overhead disk defragmentator with support for multiple optimization strategies. Besides your usual fixed disks, it is also able to defragment removable flash devices in a way that minimizes overall writes. A variety of command-line options for fine-tuned optimization are available. Started without these options, the program activates immediately and defrags all disks.

An interface that gives more control is also available: JkDefragGUI (by Emiel Wieldraaijer). Alternatively, JkDefrag Portable is also available with a custom open source GUI.

tried it on my portable hd (2tb)
it is ok, but the optimization is lacking; it does some, but not alot
in order to put the portable software first, i put everything else in an 'x' folder and ran the defrag sorting by file/folder...
...then, when the portable apps are in the first position i switched to fill.. but jkdefrag doesnt fill smartly at all, so i switched to mydefrag
... using monthly data defrag and then switching to consolidate i achieved better results... you can do a defrag only alternating with consolidate to get better results
... finally, for a portable hard drive, i recommend defrag only option, as a regular maintenance... in fact, use it as the screen saver, on defrag only, all drives

This appears to be defunct. The portable version is no longer available to download from the website, and the website for the newer non-portable version no longer exists. v3.36 is still available from https://filehippo.com/download_mydefrag/4595/.
