The defrag procedure can be scheduled for a certain time, or can be carried out when the PC is normally idle.
The defrag can be run in the background so that the user hardly notices its operation.
The defrag can be run in screensaver mode.
Zone filing: categorize different files into different zones according to their levels of use and apply different methods to files in respective zones (new feature in 12).

There are five different defrag methods: Stealth, Space, Complete/Name, Complete/Modified, Complete/Access. "Stealth" is designed for use on PCs with large files and little free space, while the "Space" method is designed for heavily fragmented drives. The three "Complete" methods (Name, Modified and Access) sort the files on your drives alphabetically, according to date last changed, and according to date last accessed.
