System Requirements

UltimateDefrag is compatible with Windows 10, 8, 7, Vista and XP (all 32 bit and 64 bit versions). Will also work with Server Editions of Windows.

UltimateDefrag will work with FAT32 and NTFS file systems with some advanced features not possible on the older FAT32 file system.

UltimateDefrag will also work with all RAID configurations. As long as Windows detects a "volume" e.g. C:, D:, then it will work. Many RAID controllers themselves determine the physical locations of the NTFS virtual clusters so we do not guarantee placement files to faster performing outer tracks however generally there is correlation between NTFS virtual clusters and physical locations of clusters on the physical platters of hard drives in RAID configurations.

UltimateDefrag also works with SSD (Solid State Drives) however since SSD's do not suffer the same physical structure limitations that slow regular mechanical hard drives you will not see any performance benefits from the file placement routines. If you wish to defragment your SSD, UltimateDefrag has algorithms optimized for SSDs where it will defragment the virtual file system while minimizing movement of data in order to minimize wear leveling.

External Drives can also be defragged. Please note that we do not recommend comprehensive defrags with USB 2.0 drives due to the slow data transfer (just do Fragmented Files Only) however UltimateDefrag shines with USB 3.0 and 3.1 drives which are generally just marginally slower than internal hard drives. You can apply all of the speed enhancing techniques to USB 3.X drives.

In general, UltimateDefrag will defragment all Windows operating systems (XP though to Windows 10) and all NTFS volumes.

It can be used on PCs and Surface Tablets.

An UltimateDefrag license will allow you to install onto 3 unique systems. For more than 3 systems, please order multiple licenses with one license for every 3 systems. 

An internet connection is not essential in order to install and activate your software. While online activation is fastest, we also provide an offline activation method that enables you to activate your license on a PC that is not connected to the internet. Just select offline activation and follow the simple step by step process.
