Local Folder View
Local View can optionally contain a separate window pane for the local directory structure. By default, the Local Folder View pane is hidden. You can show and hide it again by clicking the Show/Hide Local Folders button on the File bar.
The directory structure is presented as a tree-like folder structure, familiar from Windows Explorer. Folders that have a plus sign (+) next to them can be opened by clicking on the plus sign. Open folders have a minus sign (-) next to them and can be closed by clicking on the minus sign.
You can click on a folder to view its contents on the right hand side pane of Local View. The displayed folder shows up highlighted in the folder view.
Just opening or closing a folder in the folder view does not affect the file view on the right hand side, unless you close the displayed folder's parent folder. In that case the closed folder becomes the new displayed folder.
