Well,
FWIW,
Ran it,
although I really didn't need to defrag to begin with,
(probably due to Jill's team doing excellent job with the new defrag;
although I do miss all the pretty colors-lol-)
Basically I was at 2%, and it chopped it in 1/2-1% woo big deal. but
interestingly, I gained over 500mb of free space?
it chopped the fragged folders in 1/2, and really dropped total excess
fragments.
In summary, it did something, and as David noted, it did seem to "optimize"
the drive.
I'm by no means an expert on this, and it would take more testing to
validate any results-even if it's worth doing.
As Jill pointed out, it being undocumented; and MSFT doesn't recommend that
you need to run it, who knows.
The results are attached.
Feel free to draw your own conclusions.
I did a defrag -a -v before; and after the defrag -b.
