6 Other Options Considered

Defraggler

Top Pro

Defrag single files and folders

Option to drill down to defrag single files or folders; from within the app or from an explorer context menu. See More

Top Con

Can be pretty slow

It can take a day to complete defragging. If you run the Windows built in defragger first, then it runs much much faster afterwards. See More

Top Pro

Selective use

Allows for the defragmentation of an entire drive or, more uniquely, select areas depending on user preference. See More

Top Con

Dumb than Windows Default Defragment tool

Top Pro

Portable and convenient

The application can be run from the desktop or configured to run from a thumb drive for convenience as well as multicomputer maintenance. See More

Top Con

Dumber than Windows Default Defragment tool

Scheduled maintenance

IObit Smart Defrag

Top Pro

You can set multiple defrag schedules

You can set multiple defrag schedules and have Smart Defrag simply exit, shut the PC down, or continue monitoring. See More

Top Con

Attempts to install additional software alongside it, and installs IObit Uninstaller or other IObit software if the user selects 'default' or simply selects 'ok' without paying attention.

The package is becoming more bloated and encumbered with efforts to monetize it as it matures. The free version will continue to advertise purchasing the PRO version and other IOBit software until purchased which is understandable but annoying. See More

PleasantIxtab's Experience

Very solid and very useful Gaming defragmentation program. Optimizes on schedules and is even intelligent enough to know when you are using your system and when you are not. See More

Top Pro

As boot time degrag

You can set manual or scheduled boot time defrag. See More

Top Pro

Can set defrag pauses on specific programs

You can set Smart Defrag to watch for specific programs to be running and then pause any running defrag until this program is no longer running, such as games or game launchers. See More

Top Pro

Benefits solid state and mechanical drives alike, including systems with both types

The standard TRIM function is used to maintain solid state drives while the defragment function services the needs of the spinning platter drives See More

Diskeeper

Top Pro

Top Con

Poor tech support

The program itself is very good, but if you have a problem, you will find that tech support is non-existent. See More
