Apparently it’s safe to throw away the ‘Render Files’ (and sub-folders) from iMovie projects:
Yes, and iMovie can even delete (all) of them for you.
Go to iMovie > Preferences and click “Delete” next to Render Files (last item on the bottom for me).
Empirical evidence suggests that a typical CD jewel case weighs between 3.0 oz and 3 1/8 oz. Let’s call it 3.1 oz. I have to ship about 864 of them to Alaska. That means I’m shipping 164 lbs. of jewel cases.
Alternatively, I can move the CDs to binder cases like these:
Each of them weighs about 3 lbs and contains 324 discs. Well, really, they have 324 pockets, but as you can see, I’m loading every other pocket with the album art/booklet for the CD:
I figure I need six cases like that. That means I’m shipping 18 lbs, for a net savings of 146 lbs. Sounds good to me.
The best part is that, when I get there, I can put all six binders into deep storage, since I hardly ever listen to CDs, once I’ve ripped them into iTunes.
