Reviews & Testimonials


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 multi-disk systems.


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.


Scott Lowe describes how his IT team used the Aomei Partition Assistant 3.0 utility to extend a system volume. See why he calls the utility fantastic. Partition Assistant is a fantastic tool that quickly and easily solved our IT department’s problem.


Partition Assistant enables you to do almost anything with disks and partitions. Disks and partitions can be copied from one disk or partition to another using the Disk Clone Wizard or the Partition Clone Wizard
