There is a free converter download for Visio/iGrafx called DataAssist
MultiConverter. You fill out the little form…they email you the download
link. I have tried this several times and I love it! This will also prevent
them from having to convert each individual file. This converter will work
through folders and drives as well!! Plus, this converter works on iGrafx,
CorelDraw, AND Designer! I am so excited about this!!! Heres the link.

Once they download the Converter, the dialogue box is pretty self
explanatory. Click “Convert†and a new Visio file is created with the same
file name. IE TimTest.igx (iGrafx) now becomes TimTest.vsd (Visio). And you
will be able to edit every aspect of your diagram in Visio.
