Ken, I have looked at Disk Tools Pro but as I already have Tech Tools Pro, 
which I believe is better, I went no further.  As Peter says, the OS handles 
most things, but I still run Clean My Mac and Disk Warrior monthly as 
housekeeping measures and hold Tech Tools Pro at the ready in case of need.  
For speed and ease of use I have these and other utilities on an up to date 
bootable partition on a separate external drive, which I find to be an 
excellent arrangement.  
Best wishes
Severin Crisp
