Native compiled code. Files stream over TCP in 64 KB chunks with no overhead.
Built specifically for Windows. Uses native APIs for real-time file system monitoring.
No servers, no accounts, no port forwarding. Peers find each other automatically via UDP broadcast.
Copy share7.exe into any folder you want to sync. Double-click it. That's the setup.
Share7 announces itself on the local network via UDP broadcast on port 7731. Other instances respond immediately. No manual IP entry needed.
File lists are exchanged over TCP (port 7732). Newer files win. Conflicts are resolved by SHA-256 comparison. Deletions propagate explicitly — a missing file is never assumed deleted.
The file system is monitored in real time using Windows ReadDirectoryChangesW. Changes are detected instantly and pushed to all connected peers.
