This button changes the view to long view. This shows us the contents of the Checkexes folder. When we select a file the name will appear here. Asks us the file type. I need to touch on this briefly.
Files usually have an extension and the extension identifies what type of file it is.
So a file name can be anything followed by a period followed by the extension. This is very important because the computer needs to associate the files to some sort of program. In plain English, the computer needs to know what type of files you have in order to use those files so if you downloaded a photo from a friend your computer would need to know its a photo in order for it to show you the photo. The extension of the file is usually 3 letters or 4 letters long. I will show you some very common file extensions.
