Using the Expand and Collapse Controls
The directory tree initially displays only two levels of subdirectories
by default. To view deeper levels of subdirectories it is necessary to expand
the directory tree. Expandable directories contain subdirectories, and are
indicated on the display with an expand indicator button captioned with

already expanded. A single mouse click on the expand or collapse buttons
preceding a directory will expand/collapse that directory one level.
Auto Scroll Upon Expand
When a directory is expanded, it may be set to auto-scroll and reposition so that the expanded directories are within the window view. Set the Auto scroll tree on expand option ON (default) in the Settings notebook, Options page 2_1 to enable this feature. If the number of directories in the expanded branch is greater than the number that can be instantanously viewed, the branch parent is repositioned two directories below the top of the window.
Expand/Collapse All Subdirectories
Expanding and collapsing directories may also be performed by selecting the Expand option from the Directory menu, or with the hot keys for Expand (+) or Collapse (-). While mouse clicking on the Expand or Collapse indicator button in the display expands/collapses the directory only one level, these commands expand or collapse all subdirectories in the branch.
Note: If new directories are created outside FS/2 (such as an install program might do), the parent directory may be expanded to reread just that branch for a tree update without rereading the entire drive.
