STARS does not inherently support file attachments. Although it has been proposed on several occasions, we believe that the number of uses cases for static content is waning. Most business processes are fluid. Typically, so are the supporting documents and work product. As more organizations continue to move toward a collaborative environment, there is simply less demand and appeal for static content. We will continue to consider this as an option for future releases. In most scenarios, attaching a shareable link from an online cloud provider, and posting it in the notes of a Task, meets the needs of most users. We encourage users to use the following services which provide shareable links.
Google Drive / Google Docs
Microsoft OneDrive / Office 365
