DIRECTORY TREE USER INTERFACE HAVING SCROLLABLE SUBSECTIONS

A directory tree is displayed and a command is detected to expand a subsection of the directory tree. It is determined whether certain criteria are met for displaying the subsection in a scrollable region within the directory tree. The subsection is presented in the scrollable region if the criteria are met, so that a greater number of members of the directory tree outside the subsection can be displayed within the graphical user interface. Some of the criteria which can be used to determine whether a scrollable subsection should be used include: whether the subsection has more than a predetermined number of members; whether all members of a root node directory of the tree can be displayed if the subsection is fully expanded; and whether the subsection is at a predetermined depth in the directory tree structure.
