==== Nodes ====
Then every filename is rawly setted. You can set up a dictionary that contains, using a simple counter, the size of every filename in order. Then, using the same type of counter, get the values of the size of the filename in a correct order.


===== Root node (0x2401) =====
==== String lookup table ====
* Offset + 8 points to some unknown data.
* Length specifies how many nodes after this node belong to this node.


===== File node(?) (0x1F01) =====
===== Header =====
* Offset + 0x18 points to the file's name
 
* Length specifies the file name buffer size, including the NUL terminator.
