Does the CAD CAM software price include file translators?
As was already said, this is complicated. There are different kinds of CAD files, different types of CAD/CAM. A 2D CAD/CAM for basic 2.5D or 3 axis CNC milling usually supports DXF and sometimes HPGL, IGES or even PDF. Modern 3D CAD/CAM software usually includes the basic 3D model translators for STEP and IGES. These are generic formats and very in quality and usability. You need to compare each program individually. For example, Alibre can now import AutoCAD, SolidWorks & Rhino files directly without intermediate STEP files.
