Binary compatible
From Network Dictionary Wiki
Binary compatible refers to that data files produced by one application/system that are exactly the same as data files produced by another application at the binary format level. Binary compatible avoids many of the conversion problems caused by importing and exporting data from one system to another. For example, many applications for Windows and the Macintosh that are binary compatible, which means that a file produced in a Windows environment is interchangeable with a file produced on a Macintosh.
