Sharing files with Syncthing

Syncthing keeps a folder automatically in sync between your device and the home server (and other family devices) — like a private Dropbox, except the files live on our own server, not a company’s cloud. Drop a file in the folder and it shows up everywhere it’s shared.

  • Computer (Windows / Mac): install Syncthing (Stephen can point you to the download), or a friendlier version like SyncTrayzor (Windows).
  • Android: install a Syncthing app from the Play Store.
  • iPhone / iPad: look for a Syncthing-compatible app — Stephen will recommend one, since Apple’s rules make this platform a little different.

Syncthing pairs devices using a long Device ID (think of it as the device’s phone number). You only do this once:

  1. Open Syncthing — it shows your Device ID.
  2. Add the server using the Device ID (or scan the QR code) Stephen shares above, and approve the connection.
  3. When the shared folder invitation pops up, tap Accept and choose where to keep it on your device.
  • Put a file into the shared folder and it syncs to the server (and anyone else who shares it) automatically.
  • Files others add show up in your folder the same way.
  • “Up to Date” (a check mark) means everything is synced.
  1. Both devices on and connected to the internet? Syncing pauses when one is off.
  2. Folder shows “Out of Sync”? Give it a few minutes — large files take time.
  3. Don’t see the shared folder? Make sure you Accepted the invitation (above).
  4. Still stuck? Text Stephen — pairing is the fiddly part, and he can walk you through the Device IDs.
