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:
 
−
*3 hex bytes, the first byte's high nibble is not the same as the first byte of the file name
 
−
*13 bytes for the central part of the file name
 
−
*2 bytes for the last part of the file name.
