I agree. Diskeeper Lite is great. It is what I run and recommend.
Not sure speaking the same soft/version about
but I have tried diskeeper lite one or two years ago
and said myself never more. Why ?
1) Huge 10MB ( or so ) size, doing much less then a soft of its
size can do.
2) Ugly nagware
3) Refusing to defrag with free space under 20%
4) Its colorful defrag screen is a big theatre, but
seems quick run a sort of file unfragment only ( if even )
5) Persuades me to do it at least once every day - gain of doing it
is much less than additional effort and disc stress
6) Windows Defrag has a lot of work to done after Diskeeper claimed
to be finished.
7) Presented concept of company philosophy is not too far from my idea
about scientologists, as they are said to be.
So it is fast as the wind. But I think
"defrag /U" does the same.
