FYI another post from 2009 I found.
The iWork (no "s") applications - Keynote, Pages & Numbers - can only open AppleWorks 6 presentation, word processing & spreadsheet documents, respectively. They will not open any other type of AppleWorks 6 files or any AppleWorks 5 or any version of ClarisWorks files. The third-party application, EasyDraw, can open AppleWorks draw documents. There is nothing other than AppleWorks that can open paint or database documents.
