Does this defrag tool provide any benefits to the cached data that TS6 uses?

Greetings Bob:
I remembered you have shared your defrag tool on this list but I seemed to
have lost mine somewhere. Could you please send to my private email once
more? By the way, the defrag tool is good for TS2000i Prosuite? TIA and
regards
Have a good one

>>Regular defrags are not such a big deal.
To be clear, I think regular defrags are
important, just that they didn't have the
dramatic impact on performance that the
first first one did (in my case).
Thanks to Bob for a great tool,
BW
