Windows 11 File Sharing
Create and manage network shares with security best practices
What is File Sharing?
Windows file sharing uses the SMB (Server Message Block) protocol to allow multiple users to access files and folders over a network.
Key Concepts:
- Share Permissions: Control network access to the shared folder
- NTFS Permissions: Control local and network access at the file system level
- Effective Permissions: The most restrictive combination of both
- Administrative Shares: Hidden shares ending with $ (C$, ADMIN$, IPC$)
Prerequisites:
- Windows 11 Pro or higher (Home edition has limitations)
- Administrator access
- Network discovery enabled on private network
- File and printer sharing enabled
⚠️ Security Warning
Never share sensitive data without:
- Proper authentication
- Encryption (SMB 3.0+)
- Audit logging
- Regular permission reviews
Quick Start
- Enable network discovery
- Right-click folder → Share
- Add users with permissions
- Access via \\\\ComputerName\\ShareName
