Usually, if you want to view or edit a file with its default
program, you can just select it and click the Open button or double-click or click Enter. However, if you need more control, right-click on a file in
the File List window and select Open, Open With, or Open Containing Folder. Open With lets you choose which program to view or edit the file with.
Open Containing Folder lets you examine the file's folder with My
Computer/Explorer (and, of course, all the files in that folder).
