Defraggler — free defragmenter that works with a whole disk, as well as with separate files.

Defraggler has a useful ability to quickly and simply defragment only selected files, rather than process the entire disk as a whole. After starting and analyzing the hard disk, the program displays a list of all the fragmented files. You can select them to see their location on the disk.

Defraggler will help to monitor the movement of data on the disk — in yellow the sectors from which data are read out are highlighted, green — where it is recorded. At the end of the program, the program will issue a message. If some files have not been defragmented, this will also be reported.
