INT 21 - OS/2 v1.1+ Compatibility Box Family API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running.  Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. - DosQPathInfo
	AX = 5702h
	CX = size of buffer for information
	DX = level of information (0002h)
	DS:SI -> filename
