Anvi Ultimate Defrag used to be $29.95 meaning that in this world it didn’t download or sell all that well.

It is now freeware, well technically bundleware, so just watch out for the third party programs it will want to install. The program can not only defragment but also check disks for errors, clean up junk files before defragmenting and optimizing. Readers seem to like it bouncing from 4-5 stars.
