Do not mix and match defragment programs as each developer has it’s own idea of what order files should be in on the system and defragmenting with another developers program may well cause hundreds of gigabytes of unnecessary reads and writes moving files to a different place on the same drive with zero noticeable benefit and unnecessary operational stress on the drive potentially reducing it’s lifespan even with non SSD drives. Of course never defragment a SSD or other type of FLASH drive unless you really want to prematurely consume the limited erase/write cycles of the FLASH memory chips.
