What is the default folder for Syncthing Windows?

On Windows, the default folder used by Syncthing to store shared or synchronized files is usually:

C:\Users\<YourUsername>\Sync

So, for example, if your Windows username is Ali, the default folder would be:

C:\Users\Ali\Sync

This folder is created automatically when Syncthing is first set up, unless you specify a different path during folder creation in the Syncthing UI.

If you want to confirm or change it:

1. Open the Syncthing web UI (usually at http://localhost:8384).

2. Check the “Folder Path” listed under each shared folder.

3. You can click Edit on any folder to change the path.
