I have spent lots of effort on researching File Transfer tools on the market, I've found Ultimate FTP and SFTP to be the most flexible and easy-to-use. Now I spend less time on learning on how to use the components and more time focusing on developing our business logic layer. I will recommend this software to my friends.

I am impressed with the components in the Ultimate Studio package. I have been developing a commercial desktop application employing virtually all of components, I have found them to be amazing, easy to use and loaded with many features.
