<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? | |||
