File header:
00000-00007: Header 1UJQ00_1
00008-0000B: Number of pictures plus 1 (why?)
0000C-00011: Unknown static value : B8-0B-01-00-00-00
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 0x152 bytes long and formatted as such:
00000-00003: Preferred image file format. Should be MPO\x00, JPG\x00 or AVI\x00.
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
