5.1 Interleaved vs Deiniterleaved

Can someone explain why one would export a surround mix as an interleaved file, all six files in one? I've been doing just 6 mono file exports, then encoding them in A Pack. You have to drag and drop each mono file into A pack in order for it to work. I don't see how the interleaved 5.1 file would work. I'm probably missing something since I'm relatively new to this.
Thanks
Eric

The interleaved file has a header which explains which file goes where, just like a 2.0 stereo file will (hopefully) always put right and left in the right place, even though it appears as one file.
The end results, again hopefully, should always be the same.

Makes sense, but what is the application? Why would you bounce to one file?
Thanks,
Eric

Think of the two kinds of two-channel stereo files: interleaved, and dual-mono. Most of the recording world uses interleaved, but Pro Tools sticks to dual-mono, for various technical and historical reasons. The differences have to be addressed when delivering the file for further work or consumer playback - not difficult, but more work.

I can think of a couple of reasons to export to an interleave:
1/. Ease of Archive. It's much simpler to keep track of one file than it is 6 individual ones for starters. No chance of accidentally missing out one of the files.
2/. (Depending on your application) Ease of use.
As long as whatever host you are using can deal with an interleaved file, it becomes impossible to swap out channels by accident. Only a single file to import.
3/. Again, under ease of use, it allows you to import the file into your DAW as a single 5.1 file, making it a little easier (?) to work on.
There are downsides though...
1/. ProTools cannot deal with a stereo interleave, much less a 5.1 file.
2/. Some encoders cannot cope either - SurCode DTS-Pro comes to mind here as it will only accept 6 mono files. Same with the SurCode MLP encoder.
3/. Less flexibility in the DAW. When I use 6 mono WAV files, it gives me a lot more control over any processing or routing options I want to use.
Bottom line is that there are arguments both for and against each method of working.
