Defragler crashed while Optimizing SSD

When I set defragler to optimize my ssd half way through the process defragler crashed. This resulted with me losing valuable SSD space which I don't know how to get back. If anyone hear can help me I will be forever in you debt!!!!

Solved my problem. You have to delete the bin files that are created which are located in the home folder of the Drive

I take it you have read up on all the pro's and con's of defragging a SSD?

(in fact there are no pro's)

From my rapidly fading memory, isn't the Defraggler 'Optimize' a zero fill wipe free space?
