Studio Moral of the Day: Last SMotD we talked about exchanging sessions between different DAWs, this one’s a bit different. Let’s talk about exchanging files between Protools studios.
If you haven’t had a chance to look at the NARAS Producers and Engineers Wing info it’s probably a good idea. It goes in to further detail then I will here.
Here’s what we’re trying to avoid:

This is pretty common site for mixing engineers to get from inexperienced engineers.
Luckily for us, this is completely a file management issue. To make this as fool proof as possible, you should first consolidate all of your files if possible. This will make eliminating the “extra” files easier.
First, make sure to label all of your tracks clearly. This is a two part thing, it’ll make it easier for the other engineer to know what tracks are what, and will make it easier to see what you’re really doing in the region bin.

The gist is that only the audio files you need are in the session. You want to have everything you need in the Audio Files directory. Nothing extra there, or in the region bin. You’ll want to account for everything on your playlists as well. Usually if your sending things off to mix, you probably won’t want anything playlisted as you’ve (hopefully) made those decisions.
Now if you’re obsessive compulsive like me, you’ll still want to keep all your extra audio and the session file that accesses it, so you’ll save a copy (different then saving, or save as) of the session that you’ve been working on. Don’t overwrite the session you’ve been working on. You might want to come back to it later. The copy is what you’re sending off.
So a checklist of things to do:
1) Label your tracks
2) Consolidate
3) In the Region Bin, Select Unused Files
4) Then select Remove from Session.
5) Then Save Session Copy as and make sure to check copy all audio.
Whaalaa! Everything consolidated and clean. Ready to be sent off.
Pitfalls to watch out for:
Playlisted Files sometimes won’t be deleted.
Autocreated regions can be hidden, and won’t “let go” of the audio files.
