Why are file extensions required for both PC and Macintosh users who upload files to Blackboard?
A file extension is a set of characters preceded by a period at the end of a file name used to identify the file type. Since file extensions are required for viewing files on a PC desktop, using file extensions is a familiar concept for PC users. Although file extensions are not required for viewing files stored on a Macintosh desktop, they are required for files uploaded from a Macintosh to Blackboard. When you click on a link to a file in your browser window, the web server needs to know what application to tell your browser to launch for you. Without the proper file extension, the server won’t recognize the file type. If a web server does not know what the file type is, it tells the browser to display the file as text.
