Allows you to change which photos appear in the main window based on the folder, date, disk, or album. When you first open an archive, the main window, by default, displays all archive photos in the top folder and sub-folders in the archive.

An archive is a list for a collection of photos that you can back up. Information about an archive is stored in a .pdb file. A .pdb file contains a list of the photos, or other files, included in the archive. The file can also contain album names.
