“When you want to defragment your hard drive, you can either use the built-in Windows utility or download a more complex application, but few of them strike the right balance between functionality and ease of use.” – Softpedia

DiskTuna in action: de-fragmenting a drive

DiskTuna (formerly DiskTune) is a tiny and free disk defragmentation and optimization software, that will only run when you want it to. DiskTuna does not install background services or other crapware that slows the system down.

DiskTuna only runs on-demand.  To make maintaining your hard disk using DiskTuna as accessible as possible, it can be used from a drive’s context menu or you can use a shortcut.

DiskTuna offers an easy way to create shortcuts to defragmentation and optimization tasks.


DiskTuna offers three operation modes:

  1. Defragmentation: Moves fragmented files in to contiguous regions.
  2. Optimization: Moves frequently accessed files into the fastest region of the hard disk. Optimization also defrags fragmented files, and packs files together. Run every few months only.
  3. Compact: Packs files together to prevent fragmentation from occurring.

DiskTuna is safe: It relies on the proven and reliable Windows defrag API to do the actual file moves. It checks the volume state prior to defragmentation. DiskTuna features a VSS safe-mode to reduce interaction between defragmentation and shadow copies and a thermal monitor to protect your hard disk from overheating.

DiskTuna is capable of moving and defragmenting the MFT online.

Although the usefulness of disk defragmentation is open to debate, the author of the software, Joep van Steen, is an old fashioned guy that does believe that maintaining a hard drive is required to make a computer run as smoothly as possible. At the same time he was unhappy with defragmentation software that was available. It was intrusive, installing background services and slowing the system down, or just too limited by only offering a defrag mode.

In his spare time he created DiskTune which was well received. Due to time constraints DiskTune wasn’t maintained for years. DiskTune is now revived as DiskTuna and takes off where DiskTune left.
