Hi, new here.

We’ve worked out that if we add a .zip extension to the end of the file name so it’s associated as a zip file, extract it, it create another graffle file that we can then open as normal.

as you can see the graffle now is a directory, but it works and opens in Omnigraffle.
Anyone got an idea as to what has broken and how We can fix it? We have hundreds of files that need fixing. It would also appear that older versions of omnigraffle are not affected by this and can open the original files.
