I just want to say a huge THANK YOU. I downloaded your AOMEI Partition Assistant Standard 10.2.0 (Freeware). It has helped me. I am more inclined to purchase from #AOMEI and recommend your brand. I like your business model.

I basically gave up on trying to switch my HDD to GPT without formatting it. I downloaded AOMEI partition assistant and it switched it in seconds without deleting all my stuff! I love you! Thanks!


I don't do this very often but I wanted to say thanks for an excellent product! This was the only way I successfully merged my C & D drives. After deleting my D drive, the Expand option for C was greyed out. I used your product and it worked effortlessly and painlessly. Very user friendly. Thanks again
