====[ QWK file format ]=================================================

|
|
All of the messages in a mail packet are contained in a file named
|
|
MESSAGES.DAT. The file's logical record length is 128 bytes. The first
|
|
record of MESSAGES.DAT always contains a copyright notice produced by
|
|
whatever mail door. Messages start in record 2 and use this format:
|
|
|
|

1 1 Message status flag
|
|
' ' = public
|

'-' = public and read

'+' = private

'*' = private and read

|
117 6 Number of 128 byte blocks in message (counting the
|
|
header)
|
|
123 1 Killed message? 225 is active, 226 is killed
|
|
124 1 Conference number (0-255)
|
|
I have heard that MarkMail 2.0 uses two bytes for
|
|
the conference number, so the next byte may be used
|
|
too.
|
|
125 4 Not used
|
|
|
|
The text of message continues in the next record. You can find out how
|
|
many blocks make up one message by looking at the value of "Number of
|
|
128 byte blocks". Message text is delimited by a "ASCII 227" symbol
|
|
between lines.
|
|
|
|
The xxx.NDX files contain record numbers that point into the
|
|
MESSAGES.DAT file for actual messages. Each conference that contains
|
|
messages has its own "xxx.NDX" file. The "xxx" is the conference number
|
|
for the index file.
|
|
|
|
Each NDX file uses a five byte logical record length and is formatted
|
|
to:
|
|
|
|
