Parallel defragmentation

Hello !

I have 3 HDD in my computer, and it's boring to do them one by one. I love defraggler (even if it's long enough to defrag), and I know that usually it's in commercial version, but I will be very happy if we have the possibility to defrag HDD all together... (just by removing the test of already running defraggler for example)

If it exists in the CCleaner commercial version, I will be happy to know it too !

Thanks for reading !

Parallel support is nice, but simply remove the pre-condition check is wrong. like [removed brand name] and many others do, defrag on multiple partition on the same disk will slow down by making more seeks than necessary.

parallel on multiple disk basis not partition basis
