Please advise how to transfer P2P a 30 GB file

I have two computers with Windows 10. Preferably the simplest option, so that at the other end people with minimal IT competence can figure it out

Per rule #3, this seems to be a general home computing question and not centered around self-hosting. Please consider adding details to clarify how this involves self-hosting.

Syncthing or rsync?

17
- Syncthing is not a good solution for a one time transfer. It is likely slower as the other solutions here.

if they have minimal capacity for installing/configuring/using software, then sending a USB drive via the postal service should be a strong contender

14
The easiest I've ever used is https://localsend.org/

Very simple, just open it on both computers, select the file and click the other computer.

Syncthing? Never used it on Windows but they do have a client so it should work. That's the simplest I can think of.

12
- Works fine on windows, I keep many phones and desktops /laptops syncing with about 100gb of data.
  
  5
- OK I'll try

  Also, you want SyncTrayzor for Windows - it installs Syncthing and gives you a tray tool to manage it.

Syncthing, Resilio Sync, or one of those browser based p2p file sends e.g. https://file.pizza or similar.

If both p2p ends know how to use torrents then creating a simple torrent to share to the other peer would work fine. But that requires slightly more IT competence especially if someone needs to open a port forward (ideally you would make sure you have your own port forwarded so the other party doesn't have to worry about this).

If you're doing this more than once it might be worth setting up a simple server e.g. HFS is a nice open source/free HTTP file server, been a while since I used it but it still seems to be active https://www.rejetto.com/hfs/

- File Pizza looks fun!

- https://file.pizza thanks this is really the easiest way, I still found https://justbeamit.com

- HFS - 20 security vendors and no sandboxes flagged this file as malicious https://www.virustotal.com/gui/file/e678899d7ea9702184167b56655f91a69f8a0bdc9df65612762252c053c2cd7c/detection

  Interesting, though I suspect that is a false positive, it's happened before with that software
  
  https://rejetto.com/forum/index.php?topic=9037.0
  
  Most likely because it is a self-contained web server executable? That sort of software would seem suspicious and similar to other sorts of virus/malware.
  
  Granted I have not used it in a while but I'd be surprised if it were true, their forums and github would be full of reports of malware.

  That aside you have plenty of other options to use if you prefer to use something else.

What about a torrent? You'll have to encrypt with 7zip or something to keep it secure, but that and qbitorrent will do the trick.

- while I was looking for ways I came across a list of public announcers https://github.com/ngosang/trackerslist
  
  1
- through the public BitTorrent tracker, I'll try it too, thanks
  
  1
- Qbittorrent or Rutorrent has some kind of extension to allow single private file sharing
  
  Or can a private magnet link accomplish this?
  
  1
  
  Idk but I wouldn't risk it when it's easy to encrypt stuff. Good security is done in layers.

2p2? P2P?

- To peer, or not to peer. That is the question.

- Thanks, I corrected it

ToffeeShare https://toffeeshare.com/

It’s too big for email, and likely too big for Dropbox or Gdrive unless you have a paid account with them.

That means you’re going to have to get slightly technical. Find a freeware SFTP program that can spawn a server on the host, and connect to it from the client to download the file.

Good luck!

- I'll get tired of explaining how to connect to FTP and what it is

Syncthing.

3
- As a long-time user, not at all simple.

  Yeah it's like the least intuitive software ever honestly.
  
  Might as well just use rsync at that point haha.
  
  2
Can we talk about how utterly absurd it is that there isn’t an obvious answer to this question yet? Feels like we’ve gone backwards from the AIM Direct Connect of old.

3
Sneakernet was made for this exact situation.

3
KDE Connect should do the trick

2
- I looked, it’s only suitable if the PС is on the same network. In my case these are different cities
  
  1
- It looks optimal, thanks

If all computers are on local network you can use warpinator.

Sync by resilio. I use it between my computers and nas and between my computer and my vps and my nas and my vps, I also use it between my work and personal phone.

2
- Resilio is really good, though I generally prefer Syncthing.
  
  Resilio is hard on memory with larger folders.

  I've never had an issue but then again I don't use it for much more than movies and TV. If sync thing supports qnap I might check it out but I've been using sync since it was launched (if not soon after).

If the machines are on the same network, try LocalSend

2
- If the machines are in the same building a USB stick is the simplest option :D

  Not always if you have a gigabit connection

file.pizza if this is a one off or rare occurrence. If you're doing this regularly, there are better options, provided the person at the "source" computer is competent. A significant question is whether or not these computers are on the same network. I would recommend running a HTTP server if you don't care about privacy, HTTPS if you do. There's no need to buy an SSL certificate, self-signed is more than adequate for this purpose.

It's more complicated to set up, but the advantage is that when you're done you can send the receiving party a link they can open in any web browser, no hassle.

2
- Or use LetsEncrypt it’s free to get an SSL certificate.
  
  2
Maybe https://snapdrop.net/

For this things i use Simple Web Server

It's just one executable and you have a fully running website with your files ready to download

Pairdrop

A cheap USB stick? Sometimes sneakernet is still the simplest.

Check out QuickDAV. I think it’s exactly what you’re looking for. If you’re going across the internet, you’d have to forward a port from your router. Otherwise, if you’re on the same network, it’s really simple.

Open the file in a text editor and email the results

1
- It'll still be 30Gb though...

  10minute mails are free, just cut it up.

I recommend https://wormhole.app for the purpose. Drag, drop, leave the tab open.

1
- Haven't used it but it says right on the page you linked only up to 10 GB. Op wants 30 GB, I guess its not possible to split.
  
  2
  
  I think that limit (previously 5GB) is for files that they'll store for you. Larger transfers are P2P only.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters

HTTP Hypertext Transfer Protocol, the Web

HTTPS HTTP over SSL

SSL Secure Sockets Layer, for transparent encryption

3 acronyms in this thread; the most compressed thread commented on today has 30 acronyms.

Others have already said it but I would use localsend. Just make sure you have a good connection (preferability wired)

Pairdrop is browser based and works on ANY device with browser support

If you can RDP, just copy and paste the file from one computer to the other.
