"BTW, do NOT defrag an SSD."

Windows 10 will intelligently defragment your ssd once a month, along with a trim. It's debatable as to how much of a performance increase you will actually receive, but the danger and risks to your ssd lifespan has been far overstated, I myself defrag my ssds using the windows 10 tool and have experienced no ill effects to my system.

The real and complete story - Does Windows defragment your SSD?

[Bloody Sam Roberts]

If you own an SSD there is simply no point in worrying about fragmented files as those disks can access their storage randomly. Where traditional hard drives access sequentially.
Defragging your SSD will only increase the read/write count and thus reduce the lifetime of your disk.
