+/// byte `JUNK` chunk and a standard `fmt ` chunk, which has the extended 
+/// length if the format your provided requires it. The first `JUNK` chunk is 
+/// a reservation for a `ds64` record which will be written over it if
+/// the file needs to be upgraded to RF64 format.
+/// 
+/// Chunks are added to the file in the order the client adds them.
