	===IDX - Index===		===IDX - Index===

	Index files are broken up into 2048 byte chunks, which I will refer to as "pages". Index ~~file~~ must be at least 1 page in size, meaning the smallest IDX file will be 2048 bytes, filled mostly with null bytes(00h) if it has ~~1 or 2 indexes~~ (there are ~~60 indexes~~ per page in SHARYO.IDX for example).		Index files are broken up into 2048 byte chunks, which I will refer to as "pages". Index files must be at least one page in size, meaning the smallest IDX file will be 2048 bytes, filled mostly with null bytes(00h) if it only has a couple of "records" (there are 96 records per page in some pages in SHARYO.IDX for example).

	====Header====		====Header====

	The first 32 bytes of each page is the "header"~~. The header's first 8 bytes contain the filename, if the filename is less than 8 bytes the remaining bytes will be padded with 20h. After the name is "IDX", followed by 00h as a seperator~~.		The first 32 bytes of each page is the "header".

	~~Byte 13 (14th byte) is the "page number", starting with 01h and incrementing each~~ page.		SHARYO.IDX - First page header example
