When doing a regular get info, you will have a screen (the Inspector) that shows you some basic information about a file or folder. This screen changes as the file changes, so if you were downloading a file, as the download completes, the file displays an ever increasing size. To see this screen, use the Command key and the i key (Cmd + i). If you have multiple objects selected when using the key, you’ll see each show a summary in its own screen.
However, at times you’ll want to see a Summary Info screen, which shows information about multiple selected objects. This screen doesn’t change as the files that are selected change. To see this screen, highlight a number of files and then use the Command, Control and i keys concurrently (⌘^i) to see a screen as follows.
