Still relevant for current Windows versions: hard drive – defrag /x – consolidate free space not really working – Windows Server 2012 – Server Fault

From my answer at [WayBack] hard drive – defrag /x – consolidate free space not really working – Windows Server 2012 – Server Fault
I’ve tried many tools, starting with
defrag C: /X(which tries, but doesn’t give good results) and found out these steps give the best results:
- Perform an Ultradefrag full optimisation
- Perform a MyDefrag
Consolidate free spacescript on the drive.Note that MyDefrag (formerly named JkDefrag) is not maintained any more but the 4.3.1 version in the WayBack machine still works very well as the underlying defragmentation APIs in Windows haven’t changed.

The original MyDefrag disappeared two times (temporarily in 2014 because the domain expired, then permanently in 2017 because the domain went off-line).
Luckily, the WayBack machine at archive.org has the latest version saved (not all the links from the archive.org search page have an executable as sometimes it shows the expired domain or a non-existing redirect when the domain got off-line):

Note that chocolatey install --yes mydefrag --version 4.3.11 fails because of the missing download. See [WayBack] Chocolatey Software | MyDefrag 4.3.1.
