File & Project Interchange with Apple Macintosh
Currently, the recommended Interchange Format when working with Pro Tools 7 is AAF / OMF , with BWF media
files. Please see: AAF on page 432 and OMF on page 449 for further information and also refer to the Pyramix
Interchange Forum in the Support Section (for registered users) for regularly updated information, as well as Inter-

History
SD2 & Pro Tools 5 Sessions and Legacy Apple File Formats
Old Macintosh files such as SD2 and PT4.x and PT5.x projects files have a Mac-binary, or double-fork structure that
the PC cannot handle directly. As opposed to interchange files, PC files or new Mac files (that do carry a simple sin-
gle file structure), SD2 and PT5 projects files are based on a Data fork (the one you see in every computer file) and
a Resource fork (a hidden, second file storing all the file info). While this binary structure was actually quite a clever
and convenient move, the fact that half of the file is hidden by design makes it a very fragile cross-platform media.
A sure sign that the resource fork has been lost is when the file appears with a generic icon and is present but
unreadable. A broken binary file cannot be rebuilt.
Note: SD2 is only supported on 32-bit systems.
