Appendix A -- Drawing Interchange File Formats
This appendix describes the various file formats AutoCAD® uses to interchange drawing data with other applications. The formats presented are Drawing Interchange File (DXFTM), binary DXF, Slide (SLD), and the Slide Library (SLB) file formats.
DXF files can be either ASCII or binary formats. Because ASCII DXF files are more common than the binary format, the term DXF file is used to refer to ASCII DXF files and the term binary DXF file for the binary format.
