I wonder if it’s possible to copy a file into clipboard from windows using RDP and paste it in a local machine on Linux?
Thincast can do this but it’s not opensource software.
I haven’t used Connect between desktop machines but between phone and desktop the respective other device usually shows up in various “Share” menus.
For remote access to a Windows machine I had used KRDC and it had the capability to expose a local folder to the remote machine as a “network drive”
