ftp!? You missed my point. When you are in Windows Explorer, the right pane will show your current contents. At the bottom left, if you enable the Status Bar, you can see the total number of folders/files in the currently displayed directory.
I think it would be a good feature to do something similar in the RAdmin Viewer. It is great to now have the ability to organize connections into folders but it would also be very useful to list the number of connections for the current folder that is being displayed.
