File viewing and editing software

To see what is in a file, and possibly to modify it, various sorts of software can be used, ranging from raw binary editors/viewers to programs that perform more sophisticated analysis. File creation software will usually edit existing files as well, and File rendering/interaction software will display them in various ways.


 * Synalysis and Hexinator  are programs (related to one another) that can do raw binary/hexadecimal viewing and editing of files, but also parse them using grammar files to analyze various file formats.
