I like this product, and recommended it to some of my coworkers. One of the features I was excited to see was comparison of local directories and remote directories. That's a cool thing, as we have a server that has a config directory with lots of files and folders in it, with only a few changes needed for any particular release. Replacing the entire config directory is not practical.
DeltaWalker will not connect to the remote server using SFTP, a Solaris box. I can connect to that server with standard ssh connections, and any of several FTP/SFTP tools I have.
I did raise this issue with Deltopia, and they were quick to respond and eager to help. They wanted to test with our server. I could not give them access to our internal server, for various reasons. The problem was never resolved because I did not, and still do not, have time to chase it down.
So, it's a nice product, but one of the key reasons for my use does not work.
