Exactly, the whole this is just MFT.

Actually PerfectDisk 10 can among other optimizations it does at
Boot-time defrag, and even it changes its size to best fit a partition
when needed. Unless you have an NTFS encrypted filePerfectDisk 10
defrags *everything*, this give me the following brag right: don't blame
me for having the best defragger out there, hehehehe :-D
