−The file name seems to be stored in the file header 3 times:
−*Original file name 0x0066
−*Current file name 0x0078
−*Partial file name 0x0092
−
−The file name is stored in 3 parts:
−*13 bytes for the central part of the file name
−*2 bytes for the last part of the file name.

−The preview image is a 64x48 image stored in a 16 colour tile way, with each 8x8 tile taking up 32 bytes of the file.

−Here's two preview images I (blasty) decoded from some PPM files.

Flipnote Studio uses 3 different file extensions:
−*[[Flipnote Files\PPM|.PPM]] - these are the animation files themselves
−*[[Flipnote Files\LST|.LST]] - This is a list of the files in the current directory
−*[[Flipnote Files\PLS|.PLS]] - These are the sticker files, and the recently edited file.
−*3 hex bytes, the first byte's high nibble is not the same as the first byte of the file name
−*First location: D3 5B 20 30 39 30 39 38 34 31 43 44 42 45 42 31 00 00
