3Click once the file for which you want to see and change properties. You may need to select the file's location (e.g., Documents) first by clicking the pertinent folder on the left side of the Explorer window.
4It's a tab in the upper-left side of the window.
5This white box with a red checkmark is in the "Open" section of the toolbar at the top of the Explorer window.
