File header: 00000-00007: Header 1UJQ00_1 00008-0000B: Number of pictures plus 1 (why?) 0000C-00011: Unknown value (seems to be static?) B80B01000000 00012-00013: Total number of photos (excluding 2D dups) 00014-00017: Appears to be file size. It's only 32 bits = 4GB max. A few hundred K larger than the actual size of every file in DCIM (?) 1607971 vs DCIM/100NIN = 1441792 vs DCIM = 147560 vs files = 1409024 vs non-disk usage = 1224857 phtcache non-disk = 456024, disk = 458752 phtcache (non) + files (non) = 1680881 - 1607971 = 72910 = 72K hmm... maybe the 72910 is some kind of checksum? ( I have no clue, all these notes were probably worthless) From 0x0018, one block per picture. Each block is 0x98 bytes long and formatted as such: 00000-00003: Preferred image file format. Should be MPO\x00 or JPG\x00. The inner cam is the only one that will yield JPG. 3D pictures are taken even with screen switched to 2D. 00004-0000B: Name of image 0000C-00013: Subfolder of image 00014-0001B: Time taken based on "DS epoch" (start of 1/1/2000) (UNIX+946684800) 0001C-00023: Time last viewed? 00024-00027: UNKNOWN 00028-0002B: UNKNOWN 0002C-0002D: UNKNOWN 0002E-0002F: UNKNOWN 00030-0003F: UNKNOWN 00040-00043: File size
