File Viewer is a utility that allows you to view any file on your Mac. The program natively supports over 60 file types, can play common audio and video formats, and display many image, Web, and page layout file types. File Viewer also provides hexadecimal, text, and icon views to help you inspect the contents of each file

With File Viewer, you can identify unknown file types and locate programs that open them. The software is linked to the FileInfo.com database, which contains thousands of file extension entries. Each file that is opened in File Viewer is matched to the FileInfo.com database, and File Viewer displays a list of matched file types.
