O&O Defrag is undoubtedly the leader among disk defragmentation software. O&O Defrag 10 Professional Edition runs on the 32-bit and 64-bit versions of Windows Vista and Windows XP, as well as Windows 2000 Professional. The version 10 doesn’t work with Windows 7, unfortunately.
O&O Defrag 10 Professional Edition offers five defragmentation methods - Stealth, Space, Complete/Access, Complete/Modified and Complete/Name.
The Stealth method is ideal for defragmenting machines with tight system resources and low disk space. The Space method is recommended for defragmenting disks with heavy fragmentation. The Complete/Access method organizes files by the date they were last accessed, the Complete/Modified method defragments files based on the date they were last modified and the Complete/Name method organizes files alphabetically.
