The majority of the files are tiles, rather than bitmaps, especially up to 1998 or so. When bitmaps were supplied, these were an extra addon. Hard disks at the time were not the sort of thing to clutter up with a 9 meg BMP file. Still.
B are bitmap files, like 'prarie wind.bmp'. J are jpegs, like in Windows XP, and L are various logo files, according to assembly.
Currently, it looks like:
