I'm wondering if there is any particular benefit to having the MFT sorted by any particular sequence, whether Name, lastAccess, lastChange?
Jonib is right, the SortByName() action is only there to place the MFT. It does not do any sorting, because there is only 1 file in that zone (the MFT). The other sorting methods would produce the exact same result.
And I have the same question as well in relation to the Directory area!
The directories are really sorted, every directory is a separate entity. Directories are often accessed in alphabetical order, for example when you open a folder with Windows Explorer.
