O&O Defrag is a Windows defragmentation utility sold by German software developer O&O Software. It has won several awards by PC journals and magazines, and is certified by Microsoft for all its current NTFS-based operating systems, including Windows 2000, Server 2003, Vista, 7, and 10. 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. More information...
