An archive must be opened before any work can be done with it. To view a file in an archive click on it or select view from the edit menu after selecting a file. A dialog will come up asking for the program you wish to view it with. Type in kless, kview, or whatever is appropriate for that file. Select "Edit...Extract" in the menus to extract the selected file to a directory of your choice. Select "Edit...Delete" to remove the selected file from the archive.
