I like RSJoomla extensions. I bought few, including few copies of their RSForm Pro. Since I was very happy with the quality of their extension and support I bought RSFiles. I like it, but one feature that stopped me from using it and look for alternative is the fact there is no way to turn off the Home icon from the GUI. This Home icon takes you the Home folder, which shows all the sub-folders, regardless whether you want to show some of these sub-folders. That for me was a show stopper. Admittedly, when I raised this issue with them, i got an reply from them within few hours that I would be able to modify this option by poking and modifying the code. Something that I cannot do, or have the time to do it.
Other than that, is is not a bad effort.
