DISPLAYING THE MIME TABLE
This page displays the following parameters of your selected MIME table.
MS-DOS
- Extension
Displays the 1-10 character extension for files of this type. This field cannot have the same value for multiple
records.
- Description
Displays the textual description of the file type. It is added to the MIME content-description header field in outgoing
messages.
MIME
- Content type
The MIME content-type field has two parts. The first part, the Content-Type, should be one of the following primary
values defined by the MIME specification:
image
audio
video
application
message
- Content sub-type
The second part of the MIME Content-Type field is specified here. Many standard types are already configured into
Internet Exchange. If others are needed and are not defined by the MIME standard, create a custom value. These types
should begin with an x and a hyphen (e.g. x-custom).
- Encoding
Displays the MIME Content-Transfer-Encoding method. This method is used to encode any non-textual data so that it can
be sent across the Internet. For binary files,
base64
is the best selection. For text files containing some 8-bit data, use the value
quoted-printable.
For plain text files, select
7-bit.
A custom value of
x-uue
is included for sending messages with attachments encoded with UUENCODE to sites that cannot handle MIME. The use of
this value, however, is not recommended and should not be used when sending messages to MIME-capable sites.
- MAC file type
Displays the four-character type field in the Mac Type file header.
- MAC file creator
The Macintosh file system is much more advanced than the DOS/Windows file system. The Operating System (OS) uses the
file extension (e.g. .TXT, .DOC.) to associate an application. The Macintosh OS stores some extra information
(attributes) in the data file. There is an attribute called TYPE/CREATOR (4 bytes each) that is used to combine an
8-byte string calling for Finder INFO. This is used by the OS to determine the correct application to open the data
file.
For Macintosh users, you can also define the MAC Finder (Type and Creator) values. Notice that the Type and Creator
values are case sensitive. If you see "----" in the MAC file type
and/or MAC file creator
field, it means that these two values are not used.
NOTE:
The system administrator may not edit the different parameters through this page. He may only use this screen for
viewing purposes before and after creating the MIME table.
