I like how fast it works for transferring files between computers. It's so quick to transfer large amounts of data from one computer to another! We use this program daily at work as we constantly need to move documents back and forth between different clients. The only thing about this product that I don't really care too much for is that sometimes there will be lag when you're trying to upload or download multiple files. But if you have just two people using the software then this shouldn't be an issue. If you are looking for something with great speed to transfer massive amounts of data - go ahead and try out Wing FTP server. You won't regret it! Our IT department uses this software every day. They often send us new versions of our contracts which has made life easier for all of us.
