How to configure folder sharing on Ubuntu (GNOME)

Sharing folders in Ubuntu is essential for managing file access across multiple devices on a local network. It supports collaborative environments by enabling users to access, edit, and store files in a centralized location. Properly configured network shares ensure security and efficiency for various organizational or personal setups.

One widely adopted method for folder sharing on Ubuntu is the Samba service, which implements the SMB and CIFS protocols. This implementation allows seamless integration with Windows systems and other operating environments, making it ideal for heterogeneous networks. Through Samba, administrators can define permissions, authentication schemes, and policies that maintain data security.

Cross-platform compatibility is vital for streamlined workflows, and Samba provides the reliability and flexibility needed to facilitate these processes. By defining explicit access controls and monitoring network connections, organizations can securely share resources and simplify collaborative tasks in diverse setups.

1. Open the Files application on Ubuntu Desktop.
2. Right-click the folder you want to share and select Local Network Share.
