Doc is always a good finder of freebies but here's one not a lot of people know about..........PerfectDisk Free..........The latest version 12.5 which has had a few of the 'paid for' versions 'bells and whistles' removed.
As most knowledgeable software gurus know Raxco's PerfectDisk has been one of the leading defrag software makers for years and years. Whilst some with SSD's don't feel they need defrag software others with 'normal' hard drives should defrag regularly.............makes my machine leaner and faster, that's for sure. Also, one small tip with this piece of software..........to defrag your system files on boot just right click the drive when you get the software up and select the option. I mention this as its not easy to find.
I've been using it for a couple of weeks and its a great piece of software..........better than any other defragger out there.
and you're welcome!
