Folders can be a great way to divide estimating items into meaningful groups.
The "New Folder" button allows you to add a new folder to your estimate, or if you select the lower portion you can add a new sub-folder.
1. Select the "New Folder" button to begin.
2. You can update the information about the folder directly directly on the estimate table by selecting the square you wish.
You can click the "New Folder" button as many times as you would like, adding a new folder/sub-folder each time.
