Access levels are restrictions set by a Project Admin, detailing which type of Project Member can access a folder. Access levels can be set to: Everyone, Supervisors, and Admins.
If the level is set to Everyone, everyone within a Project can access files and folders. If the level is set to Supervisors, Supervisors and Admins can access it. Finally, if the level is set to Admin, only Admins can access it.
Access levels are a Premium feature. To see all benefits of upgrading your Project to Premium, click here.
