34 * Ok, here's how it goes. The UDF specs are pretty clear on how each data
35 * structure is made up, but not very clear on how they relate to each other.
36 * Here is the skinny... This demostrates a filesystem with one file in the
37 * root directory. Subdirectories are treated just as normal files, but they
38 * have File Id Descriptors of their children as their file data. As for the
39 * Anchor Volume Descriptor Pointer, it can exist in two of the following three
40 * places: sector 256, sector n (the max sector of the disk), or sector
41 * n - 256. It's a pretty good bet that one will exist at sector 256 though.
42 * One caveat is unclosed CD media. For that, sector 256 cannot be written,
43 * so the Anchor Volume Descriptor Pointer can exist at sector 512 until the
44 * media is closed.
45 *
46 * Sector:
47 * 256:
48 * n: Anchor Volume Descriptor Pointer
49 * n - 256: |
