Since that first Macintosh, Apple has always developed and used their own hardware specific operating system. Also, using ConceptDraw you can create your custom objects and supplement libraries to cover your requirements. Moreover, you will be able to use a huge number of business-oriented libraries supplied by ConceptDraw Solution Park. Making business drawings with ConceptDraw DIAGRAM is easier than using MS Visio. Thus replacing the diagramming software, allows to keep all your drawings, created in the old versions of MS Visio. If you used MS Visio 2003-2010 before and now is considering to switch to ConceptDraw DIAGRAM, maybe this is a good news - ConceptDraw DIAGRAM is still supported reading and writing of Microsoft Visio XML file format. The writing VDX files is no longer supported. Since MS Visio 2013 drawing files are written in the new VSDX and VSDM file formats. MS Visio 2010 and earlier versions support reading and writing files in a binary VSD or xml-based VDX file formats. It is a filename extension for the MS Visio XML drawing file format. MS Visio file with the extention.VDX can be created with the MS Visio 2003-2007.
