Old files created before extensions on the Mac became standard, and have become exec files.
I have old files on a CD (a la 1999) that were created before extensions on the Mac became standard, and have become exec files. They have never been near a Windows computer.
What is the best way to access them?
The Word files seem to be fine, so these may have been Quark or Apple Works.
Currently on an iMac OS X El Capitan. Can't remember which computer I had when these files were saved.
