This appendix describes the various file formats AutoCAD® uses to interchange drawing data with other applications. The formats presented are Drawing Interchange File (DXF™), binary DXF, Slide (SLD), and the Slide Library (SLB) file formats.
DXF files can be either ASCII or binary format. 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 is used for the binary format.
