Well,
I did decide to try the two freeware choices---both auslogics---and dirms-S---and compare it to the freeware one I have used--diskeeper lite.
Step one with both programs was to make sure both were malware free---and I installed auslogics first.---but did not run it until I had run diskkeep lite.---so it was dealing with a
well defragmented volume----and it ran extremely fast---found a claimed additional 34 fragments---but Auslogics may look better and run faster than the windows defragmenter,
but in MHO, its not a robust deframenter---it has no configeration options---but then again neither does diskeepre lite. And reading the user reviews on various download sites,
few had any negative comments on auslogics defragmenter ---but at least it was easy to install and it does have some pretty graphics and reports while it runs.
Dirms-S by contrast was a nightware to get registered---and its only a 30 day trial---after which you must register again--but dirms is a totally better defragger because it actually moves files---including system files which most defrag programs won't touch---but only two options exist---either defrag or compress---and dirms is very slow at either---but something I am likely to retain--although I doubt I will also install its companion buzzsaw.---but I will probably register on its forums to get a deeper understanding on some questions I have.
And being a client computer on a network also raises some questions I need answered.
Just the feed back I have---for what if anything my opinion is worth.
