This project aims to build a file synchronization service that allows multiple computers to keep files in sync automatically. The service will detect file changes, communicate over a network, and transfer only necessary updates efficiently.

• File Change Detection: Monitor filesystem for added, modified, or deleted files.
• Networking: Implement a server-client model for file synchronization.
• Basic File Transfer: Send updated files over TCP or UDP (haven't decided yet).

• Delta Sync: Transfer only modified parts of files instead of entire files.
• Compression: Reduce bandwidth usage by compressing file transfers.
• Parallel Uploads/Downloads: Improve performance by handling multiple files simultaneously.

• Conflict Handling: Implement strategies like last-writer-wins, user prompts, or versioning.
• Retries & Error Handling: Ensure robustness against network failures.
• Encryption: Secure file transfers (optional, for later phases).

• CLI or GUI Interface: Allow users to manage sync settings.
• Logging & Notifications: Provide real-time feedback on sync status.

• Filesystem Monitoring: Odin standard library or OS-specific APIs (inotify on Linux, FSEvents on macOS, ReadDirectoryChangesW on Windows).
• Networking: TCP sockets or UDP.
• Data Storage: SQLite for file metadata or a simple log file.

1. Implement a file watcher to detect changes.
2. Develop a basic networked file transfer mechanism.
3. Optimize with delta sync and compression.
4. Implement conflict resolution strategies.
5. Build a CLI or GUI for user interaction.

• Peer-to-Peer (P2P) Syncing instead of a centralized model.
• Cross-platform Support with OS-specific optimizations.
• Advanced Security Features like end-to-end encryption.
