Unmovable Files

[Seekermeister]

This is a question of curiousity. When going to the defragmenter, there are always two blocks of unmovable files, with the smaller block first. They have always been in the same positions on the analyses bar, but when I just went their, the larger block had moved to the far end. Is this normal, or does it indicate some kind of problem? Am I correct in believing that the smaller block is the page file and the larger the OS files? Before it moved, the space between them was kept nearly empty, but now just the opposite, and most of the program files are in the space between them.
