Why are some of the files skipped by the program?
Sometimes Disk Defrag skips certain files because they are locked by another running program. Common solution would be to exit all running applications when you defragment your disk. Some files (MFT, etc.) are skipped because they are system files and cannot be defragmented by this program.

What is MFT?
Probably the most important of the key system (metadata) files that define an NTFS volume, the Master File Table or MFT is the place where information about every file and directory on an NTFS volume is stored. The MFT is in essence a relational database table, containing various attributes about different files. It acts as the 'starting point' and central management feature of an NTFS volume--sort of a 'table of contents' for the volume, if you will. It is somewhat analog to the file allocation table in a FAT partition, but is much more than just a list of used and available clusters.
