Having recently attempted to repair several corrupted folder files, I
would say that the file structure appears to be fairly simple: a
sequential file of message texts with each message preceded by a
four-byte offset pointing to the beginning of the next message in line
(or, construing it another way, a four-byte count of the length of the
current message--you have to add 4 to get the actual offset).
I guess I don't have any really large folder files, because I have no
problem with the speed of Yarn's processing (I use the OS/2 version of
0.91, by the way.)
