Use the Open As box to tell the ProtoTRAK PMX CNC what kind of file it is
Use the Open As box to tell the ProtoTRAK PMX CNC what format the file is in so that
it knows how to convert it to the ProtoTRAK PMX CNC format. In the image above, the
ProtoTRAK PMX CNC could guess that the file to be converted was from a previous
version of ProtoTRAK because of its file extension (.mx3). But since file extensions may
be missing or may not really describe the file format correctly, you can use the Open As
box to declare the file type.
The drop-down menu in the Open As box shows which converters are available. If a
converter is not listed, you can check to see if it is activated (see section 3.1.6).
14.9.3 Converting From the ProtoTRAK PMX CNC to a Different Format
Files, or programs, are converted from the ProtoTRAK PMX CNC to a different format
using the Save function of Program In/Out Mode.
