Nearby Share is Windows 11's built-in AirDrop-style feature for sharing between Windows devices on the same network.
- Open Settings → System → Nearby Share → Turn On
- Set to "Everyone nearby" or "My devices only"
- Right-click any file → Share → select the nearby PC
Note: Only works between Windows devices. Does not work with Android, iPhone, or Mac.
Method 3: SMB Network File Sharing (Windows 10 and 11)
SMB (Server Message Block) lets you share folders across a local network. Best for home or office setups.
- Right-click the folder you want to share → Properties → Sharing tab
- Click "Share" → add users → set permissions
- On the other PC, open File Explorer → Network → find the shared folder
SMB uses ports 445 and 139. Make sure these are open in your firewall.
