We begun working on a file transfer mode.Jose Torres commented
This was posted by 2014 and is already 2016. I do not know what is the limit of the clipboard copy/paste mode to transfer files, but I do know that this method can only be used on full control of the remote desktop. The feature will be nice for transferring files without having the control of the remote desktop. The user can be using their computer and at same time I could connect without viewing the desktop nor controlling the keyboard/mouse, browse the folders and copy/retrieve files.
