Publisher's description
From O&O Software :O&O Defrag V4 offers the most professional and user-friendly features ever. It is now optionally integrated into the Microsoft Management Console, which is the Windows administration tool, also available for Windows NT 4. O&O Defrag V4 can therefore also be installed without using the MMC or, alternatively, locally configured GUI-less with the new command-line interface. O&O Defrag V4 emphasis its leading position in the field of Windows defragmentation with the new integrated STEALTH technology. Our STEALTH technology is an industry first that is distinguished by a uniquely minimized demand for system resources. O&O Defrag V4 reactivates the lost and hidden system performance and brings it back to save time and money. File- and database servers, but also workstations can substantially improve their system performance using O&O Defrag V4. Regular defragmentation prevents new hard disk fragmentation and will ease the use of Windows XP/2000/NT in the long term.
