Thanks. i do not know what kind of extension it had. Only that is a project created in andesk top publishing program, don't know which one. Only have disk and cannot open itIf it was on a floppy, then its almost certainly an old file from the OS9 days.
Many mac users never needed to add an extension to the file back then, so unless it has a file extension like filename.tif or filename.doc it's a guessing game as to what created the file and what type of file it is
