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.

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/. |
Defraggler improves drive performance by organizing data at a file system level. Since files over time spread out over a drive, occasional "defragmentation" can help reduce drive seek time. Uniquely, Defraggler can function at a file or folder-level to help clean up specific areas, or the whole disk. The program will also list fragmented files and their locations.
The package includes both 32-bit and a 64-bit versions, as well as a command line program. This tool is not recommended for SSD drives or other flash-based media.

For quick-and-dirty, single file specific defrag job, I tend to favor Sysinternals' Mark Russinovich CLI implementation (as in Clean-and-Lean-Interface...;-) |
WinContig is an easy-to-use file defragmentation program that allows defrag of parts of the drive. This is useful for squeezing extra performance out of important or frequently used files or programs without wasting time and energy cleaning up the rest of the drive.
Note that this is recommended only on magnetic disks. Flash-based drives (SSDs and thumb drives) don't benefit from defragmentation and such maintenance tools can reduce the life of the drive.
The program engine is based on the standard Microsoft defragmentation API and allows you to group files into profiles, accepting a number of available command-line switches for additional control.

Sysinternals' lean Contig.exe v1.8 (248KB) CLI will defrag selected files just as well…;-)

Although a little difficult to figure out, have successfully used this to defragment fragmented .ISO files resulting from an AnyBurn .IMG file conversion.

WRT __philippe post (2018-09-12 08:35) on sysinternals CONTIG v1.8 : |
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.

Because of the different strategies of most defrag apps you can do more false then right:

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.

Avi-aryan: on the Boot Time Defrag, it's unfortunately still only available for the installed version. |
PageDefrag allows you to defragment files that are normally not possible to defragment i.e. paging files, registry hives, event log files and Windows 2000/XP hibernation files. In addition, it shows the fragmentation level of these files so that you can make a decision about whether or not to defragment.

The download link does not work; available from the website ie here: http://technet.microsoft.com/en-us/sysinternals/bb897426.aspx |
HDiskDefrag defragments FAT/NTFS partitions on non-removable hard disks. You can specify to clear temporary files and browser cache before defragmentation. You can also select whether to defragment system files and various methods of placement (by name, last access, last write).
Not recommended on SSD or flash-based media.
