Alan Fan of Resilio

Hi I do something similar, using the free license. I have a folder on each desk top called "Desktop Shared Folder" which is shared through Resilio Sync I also set up a remote desktop connection between the computers. I use Google Remote Desktop. So when I am sitting at A and want to archive a file on B, I do the following. On A move (or copy) the file (or folder) to the Shared folder. watch the History on the Sync menu bar, wait until syncing is complete use remote desktop to control computer B to move the file from B's copy of the shared folder into the required filing place. In the case you mention you would need to tell your grandfather to ignore you moving the mouse icon remotely!
