IntelliWrite™ fragmentation prevention technology. New!

Yes

IntelliWrite prevents up to 85% of the fragmentation every system suffers from. It intelligently writes contiguous files to the disk so system resources are not wasted creating fragmentation. The results? A whole new level of system speed and efficiency.

InvisiTasking® technology

Yes

Diskeeper’s revolutionary new InvisiTasking technology guarantees that Diskeeper will use only system resources that would be otherwise be wasted (idle time).

This technology allows Diskeeper’s real-time defragmentation to continually keep your disk volumes in top shape, and ensures your computer's performance is never slowed down by the defragmentation process itself.

With new enhancements to InvisiTasking, Diskeeper will defragment even faster on active systems and systems running idle-time tasks such as SETI@Home, etc…

I-FAAST® 2.0 file optimization technology

Yes

Intelligent File Access Acceleration Sequencing Technology [I-FAAST] 2.0 improves file access and creation on NTFS volumes by up to 80% above and beyond the improvement provided by defragmentation alone.

When I-FAAST is enabled on a volume, Diskeeper runs specially-engineered benchmarks on the selected NTFS volumes to learn their individual performance characteristics. (Not all disks have the same characteristics.)

Diskeeper then transparently monitors these volumes for file access frequency on an ongoing basis in to determine which files are requested most often. Special analysis techniques prevent Diskeeper from being "fooled" by files that have been recently accessed.

Terabyte Volume Engine™ (TVE) technology

Yes

Terabyte Volume Engine (TVE) provides fast, safe and complete defragmentation of large volumes with millions of files for incredible performance on large drives.

Thorough free-space consolidation

Yes

Diskeeper will consolidate approximately 90% of the volume free space into a dozen or less large free space segments, improving write performance for large files.

Intelligent Defragmentation

Yes

Diskeeper’s logic controller, which detects various volume and system conditions and chooses the most effective algorithm, has been re-designed to deliver performance benefits faster and more efficiently.

Defrag disks with less than 1% free
space

Yes

Diskeeper defragments hard drives in the most extreme of conditions — even if your computer system has only a one or two percent of free space left available, Diskeeper can restore lost performance and save the applications reliant on those files from major reliability failures.

Defrag severely fragmented files

Yes

Even if your computer system has a file in millions of fragments, Diskeeper can restore lost performance and save the applications reliant on those files from major reliability failures.

Power Management for Laptops

Yes

When this option is enabled and the computer switches from normal power to battery power, any ongoing Automatic Defragmentation is safely postponed and a message noting this is written to the Windows Application Event Log. A message is also displayed informing you that Automatic Defragmentation has been postponed. When the computer switches back to normal power, Automatic Defragmentation will resume.

When the computer is running on battery power, any ongoing Manual Defragmentation jobs are canceled and a message noting this is written to the Windows Application Event Log. If you start a Manual Defragmentation job when this option is enabled (and the computer is running on battery power), a message is displayed asking if you want to continue, even though running Diskeeper on battery power may reduce the available battery time.

Volume Shadow Copy Service (VSS) Compatible Mode

Limited

Yes

Diskeeper eliminates the need to choose between the benefits of VSS and defragmentation. The new VSS-compatible mode in Diskeeper affords you the ability to leverage the data protection of VSS and the performance and reliability of Diskeeper defragmentation.

When the VSS defragmentation option is enabled, Diskeeper uses proprietary defragmentation engines to help reduce the chance of the defragmentation operation causing new VSS snapshots from being created, thus potentially preventing older snapshots from being purged.

Real-Time complete defragmentation

Yes

Real-time defragmentation automatically handles fragmentation as it occurs, providing maximum system performance at all times!

Boot-Time Defragmentation of Critical System Files

Yes

Safely performs Microsoft®-recommended defragmentation of critical system files to improve performance and reliability.

Automatic Directory Consolidation

Yes

Automatically performs the additional processing necessary to move all the directories on each volume into a single location on the volume. This setting affects both Automatic and Manual Defragmentation operations.

Defragment All Volumes Simultaneously

Yes

Diskeeper can analyze and defragment more than one disk volume (hard drive partitions) at a time. This includes a backup hard drive attached to the computer, but does not include network attached storage devices or other computers on the network.

Historical Reporting

Yes

Diskeeper can provide useful information about file performance loss on your volumes, and also historical data about the fragmentation levels on your volumes. To do this, Diskeeper relies on performance and defragmentation data collected from your volumes.

Real-Time Dashboard

Yes

The Dashboard tab displays real-time details about Automatic Defragmentation, the health of your volumes, the idle resources that Diskeeper uses to accelerate volume performance, and other useful defragmentation information.

Intuitive Control Panel

Yes

The Dashboard Control Panel displays real-time details about automatic defragmentation, the health of your volumes, the idle resources that Diskeeper uses to accelerate volume performance, and other useful information.

64-bit Operating Systems Support

N/A

Yes

Diskeeper works with 64-bit operating systems such as Windows Vista Business, Windows Vista Ultimate, Windows Vista Enterprise, Windows XP Home, Windows XP Professional, Windows XP Media Center, Windows XP Tablet PC, and Windows 2000 Professional.
