A branching view is a new view derived from an existing view. When a branching view is created, StarTeam shares items from the parent view into the child view. The child view knows that the items came from the parent, but has no idea where the parent got them. For example, if a folder was shared to the parent view from another project, the child view does not have a similar share to the other project. If that is needed, the folder in the child view should be deleted and the folder should be shared to the child view from the other project (just as it was once shared to the parent view).
Similarly, if a folder was shared from the parent view to another project, or to another location within the parent view, the corresponding folder in the child view would not have that same relationship with the other project or view folder.
