Files not moved to the beginning of the partition

On NTFS partitions, a portion of the free space is reserved by Windows NT for the Master File Table (MFT). This free space is usually most noticeable at the physical "beginning" of the partition (easily seen using the graphic fragmentation analysis display), but space is also reserved for use by the MFT in other areas of the partition. Note: If the partition was converted from FAT to NTFS, the MFT may be anywhere on the partition.

Since this free space is reserved for exclusive use by Windows NT, Diskeeper will not move files into these areas of the partition. However, Diskeeper will move files out of this reserved area.

Note: In versions of Diskeeper prior to version 2.0.138, space that was allocated to the MFT but not yet used appeared in the graphic fragmentation analysis display as gray. This could create confusion, because it appeared there was more free space than actually existed. Since Diskeeper v2.0.138, this unused MFT space has been represented by green diagonal lines.
