You can use folders to group and organize items for a specific project and share project information with team members. For example, you may want to group requirements for a new feature in folders so you can track progress and communicate information to others.
You can display important messages and a web page related to a project on the folder Details tab. For example, you may want to provide schedule updates, milestones, or information about the next build or display a wiki related to the project. See Adding folders.
The folder Contents tab can also display time tracking information in columns, such as estimated and actual hours and percent complete. This information can help you monitor progress of individual items and overall calculations for all displayed items.
