Standard MIME type string. For example, text/plain.

A user-friendly description of the MIME type.

If checked, the type represents textual content editable in the Freeform Editor.

The default file extension for this MIME type. For example, .txt.

The type sent to the browser when the file is viewed. This field is optional. If you do not supply a value, the default value, the name, is used.

Select the file type used to filter (parse) data of this type. When no filter name is specified, this column displays “Not Translatable”

Select the filter configuration used for data of this type. This option allows you to specify the desired filter configuration when you have multiple MIME types using the same file type definition. This can be the case with XML or other meta-formats. The filter configuration you select will be the default for the MIME type.

List of all the possible file extensions for this MIME type. For example, .txt and .xsl.

Specify the name of the application used by the Launcher for this MIME type.

Specify the executable for this application, and whether the application is a “Singleton” — that is, whether it runs as a single process when you use it to open multiple files. For example, Notepad starts a new instance for each file you open. It is not a singleton. Word, however, runs just one process regardless of how many files you open; it is a singleton.
