"He who marches out of step hears another drum." ~ Ken Kesey
So....you also look for old files. Those could be files created by Macromedia, or gasp... Aldus FreeHand or other outdated graphics apps on pre-OS X systems the new Mac can't read. Its odd the .exe extension is added however. Many older Mac apps didn't add an extension to the file name, such as .fh in the case of FreeHand, so that could explain the .exe extension.On another note, I always thought FreeHand was superior to Illustrator. Thus just one of the reasons Adobe needed to acquire Macromedia and kill it.
Have you tried the trick of renaming the extension to .eps or.ai or .ps?
OK, I just transferred the file to an older machine running OS 10.4, and like magic, they became Illustrator CS3 files!Steve
