Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.</span>
The standard program that uses common views such as the icon view, list view, and details view would be the program known as "File Explorer" (Windows) or "Finder" (Mac). This program uses all the views to make selecting and tracking down certain files a much more painless and easier process to complete.
Hope this helps and good luck! :)
