This is a 16GB Nexus 7 The listed items only add up to a little over 9GB. So 4GB worth of files are missing.
How can I find those missing files?

1You mean, your Nexus 7 is 16GB but appears only 13.2GB? – Markissimo Nov 09 '12 at 10:35

@eldarerathis I see. Just saw the screenshot saying 13GB and him saying it's the 16GB version I immediately assumed that's the problem. – Nov 09 '12 at 15:03

If the displayed detailed would be complete, you'd be correct: 1.28G + 7.28G + 200K + 282M + 762M = 9.6 GB total space -- while the summary says 13.24G. Explanation is easy: The details list is not complete. It e.g. misses Cache, temporary files, log files, tombstones, and probably some more.
Where to find those? In the file system, and for completeness this requires root. For some more details, please take a look at corresponding questions by following the tags internal-memory and storage. A good source to start with is the question Something is secretly eating up my tablet memory and I need help finding it.

The linked article should get you started -- most needed details are covered there. Feel free to let us know where the gross of those ~3.6 GB were located. Btw: The screenshot information looks a bit misleading to me: "Apps (app data & media content)" could be interpreted to mean the data only, excluding the
.apkfiles. So in case you cannot get together the missing space otherwise, consider to check that as well. Oh, and if you use App2SD, it might also be the "decoded.apkfiles" on internal storage... – Izzy Nov 09 '12 at 16:24
