Which feature provides users the ability to attach resources and documents directly to tasks in Smartsheet?

The Attachments feature enables users to add relevant resources and documents directly to specific tasks within Smartsheet. This functionality allows for enhanced project management by providing easy access to important files such as specifications, proposals, or reports that are associated with a particular task. When users utilize the Attachments feature, they can upload files from their local devices, link documents from cloud storage services, or attach files directly from other applications, ensuring that all necessary information is centralized and easily accessible.

In contrast, while the Notes section allows for additional comments and observations related to a task, it does not support the attachment of documents. Task history provides insights into changes made to the task, including updates and comments, but again, it does not facilitate file attachments. Resource allocation focuses on managing and assigning resources to tasks but does not deal with document attachments at all. Hence, the Attachments feature is specifically designed for attaching files, making it the correct choice.
