I started using this to move executable files from my laptop into my Pebble watch. Since the Pebble "install" works on the same port as opensim, and Im always running a server there, this works better for me. Also, I dont like giving my files to Dropbox. Plus, this is cross platform! Wonderful app! I also use it to view company documents on various machines in my home and office, since they are not shared to any central server.
