find myself mistaken but not resolve it.
Line 1: Line 1:  +
<pre>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
