I do:
- Wormhole.app: for smaller file transfers to people not tech savvy
- Rsync: if the person is running an SSH server I can connect to
- Bittorrent: pretty much anything else
Me and a buddy just set up syncthing and use that when we need to do this and don’t want in third parties involved. Turn it off when you are done.
No love for SwissTransfer from Infomaniak. Shame.
BitTorrent
VPN server and any NAS or other network file share.
