The main window consists of the normal Windows interface (title bar, menus, etc.) and three functional areas, as shown below:
The toolbar provides short cuts to several frequently used commands.
The folder tree displays disks and folders from which you may select a folder to display. Unless disabled from the Tree menu, folders are color-coded to indicate the presence of previously thumbnailed images.
Selecting a folder works much like Windows Explorer; most operations and menu short-cuts work similarly, and you can drag-and-drop selected files to move or copy them to different folders and drives.
When you select a folder from the folder tree, file names (and thumbnails, if generated), display in the thumbnail view.
You may also drag the selected files to a new folder or disk.
