File is "is an older Mac file and must be updated on that platform". What is this?
Question: Why does it say "*.vnc is an older Mac file and must be updated on that platform"?
Answer: This message will occur when GibbsCAM is unable to recognize the file being opened as a GibbsCAM part file. This can be an indication that the file was transferred from a Macintosh system without first being updated.
However, in most cases this message occurs when a file has been renamed with a .VNC extension. If you are unsure open the file in Wordpad by right-clicking on the file and selecting 'Open With'. If the file does not start with RFIL it is unlikely it is a GibbsCAM file.
You can also get this message when a file has become badly corrupted. If you had a crash while saving your file it is possible the file has been corrupted.
