| id | U32 | 4 | 0x000 | File ID, useful for files without a filename entry
| filename_offset | U32 | 4 | 0x004 | Offset into the filenames table (ID 0x200) where this file's name is located
| flags1 | U32 | 4 | 0x008 | Flags including encrypted flag, etc
| flags2 | U32 | 4 | 0x00C | Flags including encryption key index, etc
| offset | U32 | 4 | 0x010 | Offset into PKG to find the file
