Media Reviews

As partitioning software, Aomei Partition Assistant is as good as any program I’ve seen.The standard version is more than adequate for most users, and the pro version is as good as it gets. I have some nits concerning, but the Windows To Go trick trumps those gripes big time.

AOMEI Partition Assistant Standard (formerly Home) Edition would seem to be the most powerful and capable freeware disk partition utility we've tried. It's highly recommended for all users, and especially those with multidisk systems.

Aomei Partition Assistant Standard is an easy-to-use tool to help you set up and manage partitions on your PC's hard drive. The program provides all the functionality you'd expect, and some you might not.
