How to Choose a File Type Extension

  • مقالة

File types are identified by a file name extension. Before defining a new file type, you should first choose a file name extension.

Instructions

Step 1:

Choose a long file name extension that you want to use to identify the file type. For more information, see File Type Handlers.

Step 2:

Check the Internet Assigned Numbers Authority (IANA) MIME database to determine whether the file name extension is already associated with another application.

Step 3:

Define a MIME type when defining a new public file type, and register it with the IANA.
