Easiest and most secure way? Mail (or hand deliver) a flash drive. That’s how they transfer data between super computers and data centers. (AWS even has dedicated trucks to do it)

Could send it over ATP - Avian Transfer Protocol.

Does require a USB stick and for your friend to train a pigeon though.

In one go? Look at Wormhole

But both ends must stay online until it is complete.

I would use syncthing for this

I use Syncthing for this things, you can even set a folder and keep it in sync with multiple users because it uses P2P

Don’t put FTP on the Internet if you don’t know how to secure it.

If you’re relatively nearby, you could just use a flash drive. Or mail one. If not, the other comments have good suggestions.

yep, id use sftp. my mail provider (proton) also gives me like 500gb in a ‘drive’ which is great for transfers like this

Btw: Might be that you’re behind a NAT (router) and that’s why bittorrent doesn’t connect. You’d need to figure out which port your torrent client is configured to listen on and then do “port forwarding” of that port to your machine in the router you got from your ISP. Or use something like UPnP that does this automatically.

Not sure if that applies in your case and it’s unsolicited advice… But a fairly common issue with bittorrent.

Syncthing

I would use Resilio Sync. It uses bittorrent under the hood. https://www.resilio.com/individuals/

Magic Wormhole protocol. There’s a lot of clients out there. Here’s some:

• https://github.com/magic-wormhole/magic-wormhole
• https://github.com/schollz/croc
• https://github.com/magic-wormhole/magic-wormhole.rs

There are website services where you both stay online and transfer directly.

There could be direct peer to peer transfer tools that are more robust.

If you want to go through a file transfer/hoster

• no limit https://gofile.io/
• 300 GB limit https://1fichier.com/

There’s some more, those are the top two in my bookmarks.

You’d do good of encrypting/7z-passwording if you don’t want others to see the content, just to make sure not to have to trust the hoster.

maybe SimpleHTTPServer (python) on the host and curl -C on the other machine?

Create a multi-part archive (…probably about 250 parts…) with a strong password, upload each part to whatever the current equivalent to Megaupload is, and let them download it at their leisure.

With no accounts on either end, should only take about three months for each to be complete.

Alternatively, you could put it on a thumb drive and drive it over if they live fairly close.

My lazy way is NGINX with autoindex.

If it’s to go over untrusted network (e.g.: internet, school network) I use SSH for port forwarding. Lazy encryption.

Something like this works just fine:

worker_processes 1;
daemon off;
events {
}
http {
        default_type application/octet-stream;
        server {
                root /storage/emulated/0/sharedfile;
                listen 127.0.0.1:30000;
                location / {
                      autoindex on;
                }
        }

}

sharedfile is a directory with the files.
On remote machine if I am not mistaken

ssh -L 127.0.0.1:8080:127.0.0.1:30000 username@host

Then just access it in web browser on 127.0.0.1:8080 or whatever port you chose.
In PuTTY you can find this under “Tunnels”.

Of course, you need to have SSH server set up as well.
