Diskeeper Pro Premier is a powerful defragmentation tool that you can use to free space on your hard drive and keep your hard drive in top notch condition.

The program's interface is clean and easy to navigate through. You can select a volume and access several methods from the context menu.

Thus, you can initiate IntelliWrite (prevents fragmentation from occurring on all volumes where it is enabled) or automatic defragmentation (maximizes the volumes' performance).

You can also use I-FAAST (accelerates file access), boot time defragmentation (processes files that cannot be safely moved while Windows is running) and SSD volumes.

In the volume list you ca view the file system, size, free space and status for each of the aforementioned methods, in the case of every volume present on your hard drive.

In the dashboard you can check out fragmentation prevented by IntelliWrite, eliminated by Instant Defrag and by defragmentation, total fragments prevented in the current second, a log file, history, and others.

Furthermore, you can perform an analysis, use manual defragmentation and configure properties when it comes to file exclusions, event logging, power management, volume shadow copy, data collection, display behaviors, proxy settings, permissions, new volume detection and defragmentation (e.g. efficient or extensive automatic defragmentation, set CPU priority).

The program uses a moderate-to-high amount of system resources, includes a comprehensive help file with snapshots and didn't freeze, crash or pop up errors during our tests.

Since Diskeeper Pro Premier comes bundled with advanced, professional settings, we mainly recommend it to experienced users.
