In Odoo, when you attach files to Sales Orders, Purchase Orders, or other documents, the system only provides a basic attachment functionality. Users can view a small icon or thumbnail representing the file type, but a full preview of the file content is not displayed within the interface. To see the complete content of the attached file, users must click to download or open it in a new tab or an external application. This limitation can hinder quick file reviews, making it less efficient for users to access detailed information without leaving the Odoo environment.

This streamlined preview functionality is embedded within Sales Orders and Purchase Orders, enabling a more efficient review process. Users can quickly inspect the contents of attached files, improving workflow efficiency and enhancing the overall user experience by keeping all necessary information accessible in one place.
