A Folder is a container for organizing FlexDeploy projects. A Folder also provides a construct for identifying characteristics that apply to all sub-folders contained within it (e.g. security, approvals, notifications, and windows).
FlexDeploy comes pre-configured with a single root folder called FlexDeploy. Folders and projects are created inside of the FlexDeploy root folder.
Maintain Folders
Folder security can be managed similar to Project Security, except Folder security setup applies to all folders and projects under it, unless overridden by a project / folder inside.
