How can System Administrators control file attachment permissions in Smartsheet?

System Administrators can control file attachment permissions in Smartsheet by configuring sheet settings based on user roles. This approach allows administrators to define what different users or groups can do within a particular sheet, including whether they can add or view attachments. By assigning specific roles, such as Editor or Viewer, Administrators can manage permissions tailored to their team's needs.

This method enables a more structured and secure environment, ensuring that only authorized individuals can attach files, thereby maintaining the integrity and relevance of the content being shared across the organization. It also fosters collaboration while preserving the necessary control over sensitive documents and attachments.

The other choices provided do not adequately address the comprehensive control over attachment permissions. Limiting file size pertains to upload constraints rather than user permissions, and requiring approval for attachments, while it may create an additional layer of control, is not an inherent feature directly linked to user role settings. Lastly, preventing certain file types from being uploaded focuses specifically on file types rather than user permission levels related to attachments as a whole.
