This is one of many tests. This test is being added because of an obscure bug that, in very unusual circumstances, a data file can be truncated, and the fact not noticed by the data library. So the fix involves a function that checks file sizes. There are also many, many tests relating to file contents. But for this test, we care about file size. Thanks!
