I’m trying to improve the previews for mail attachments. The content type in a mail describes the attachment. Some old mails have “x-mac-type” and “x-mac-creator” set. But I don’t understand the format of this information. In the horror cabinet of my old mails I found some examples:
[quote]Content-Type: application/octet-stream; name=“MA script 1”
; x-mac-type=“54455854”
; x-mac-creator=“54424236”
Content-Type: application/octet-stream;
x-mac-type=52624246;
x-unix-mode=0644;
x-mac-creator=52427632;
x-mac-hide-extension=yes;
name=“otrTemplate.rbo”
Content-type: application/msword; name=“Membership Renewal 2002?3”;
x-mac-creator=“4D535744”;
x-mac-type=“52544620”
Content-Type: application/octet-stream;
x-mac-type=54455854;
x-unix-mode=0644;
x-mac-creator=522A6368;
name=“XERDBeta1Notes”[/quote]
One attachment has a file ending (rbo) and one a mime type (msword). I know that the other attachments are text files. But how do I decode the values of “x-mac-type” and “x-mac-creator”? It’s not base64, not hex and not ascii. What else could it be?
