Netiquette - Basic File Extensions Reference a to m - Via Netiquette IQ



File extensions

There are many file extension which have been used over the  years. A considerable amount are now defunct and not used. Good Netiquette IQ espouses not sending formats which are uncommon. All attachments should also be identified in the text of the email itself. An email should never be sent which requires a custom program to open it unless it is expected. The following is a compilation of file extensions which are hopefully contemporary. If any reader identifies an outdated extension, please let us know. This list has extensions from a to m.
List of File Extensions

        File extensions are based on utilizing all possible combinations of English characters.  Three alpha characters shows a possible combination of close to 20,000 possibilities.  If numbers or additional letters are added, far more combinations are possible.  There are a number of categories for file extensions.  Among these are compression data archive, media archiving, computer aided design, database, fonts, graphs (vector, 3D), object code, source code and music.  There are more categories for scientific, video, games, medical and more.  The following list shows most of the formats used in common email.
