If you have a regular mechanical hard drive, do this each time you install software on your PC.

When you install any software it usually installs with significant fragmentation which reduces performance before you even try to run the program. If you have UltimateDefrag V6 installed, perform this simple command prompt step to maximize performance of any software, game or simulation that you install.

Viewers, please note that this only applies to mechanical hard drives.

For SSD's, if you are a purist, at the microsecond level, file fragmentation can slow down an SSD - because the virtual file system is fragmented. Each fragment is an extra input/output operation. You won't perceive in on an SSD but if you are a purist then yes, fragmentation does slow down SSDs at the microsecond level.

Generally it is not necessary to defragment a solid state drive.

You need UltimateDefrag V6 to be able to issue the commands mentioned here.
