Have you tried the NKN Direct File Transfer by community developer Lynn? It runs on NKN network, is end to end encrypted (as well as hop by hop encrypted), free, and pretty fast (up to 10Mbps between any points in the world). Give it a try and let us know how you think!
Using your web browser, pick a file, and create a magic link. Keep your browser tab open.
Send the magic link to your receiver(s).
The receiver(s) open it in a browser, and puff the file is transferred directly between sender and receiver(s). You can see the progress of file transfer in terms of total size as well as percentage transferred.
And Voila, a file is transferred securely and directly between sender and receiver’s browser without using any 3rd party cloud storage!
