AppleWorks does not run on present-day Macs, and there are only limited options for opening its files.
- Word Processing documents can be opened directly in Pages 4 (AppleWorks 6 only) but this is no longer available - the newPages 5 (Mavericks required) does not open AppleWorks documents. Panergy Software's docXConverter v3.2 ($19.95) can convert Appleworks 5 and 6 Word Processing documents to RTF (though it has been reported that it can only handle documents which contain only text, not those which include images or frames). The latest version of the free LibreOffice has announced that it can open AppleWorks 6 Word Processing documents and an ability to open ClarisWorks documents has been reported: it does appear to be able to handle at least some embedded images.
- Draw Documents can be opened directly only in EazyDraw (the more expensive version from their website, not the cheaper one from the Mac App Store, and you will need v4.0 'Retro' not the most recent version) or Intaglio (though this appears not to be able to handle very complex drawings). LibreOffice will open simple Draw documents but I found it very unreliable with complex ones.
- Spreadsheets can be opened directly only in the older versions of Numbers - the new version for Mavericks will not do this. The old version is no longer available.
- Presentations can be opened directly only in the older versions Keynote; again, the new version for Mavericks will not do this. The old version is no longer available.
- Nothing will open Database files.
If you are able to run AppleWorks on your Windows PC you should take the opportunity to convert the files to RTF or Word format for Word processing and Excel for spreadsheets. Databases you can only export as ASCII files which you can then open in another database program: you will of course lose all formatting and the results of calculations will be preserved in fixed form, not the the calculation formulae themselves.
Success has been reported in running Snow Leopard Server under emulation in Parallels - the method is described here: Snow Leopard Server is available in the Apple Store (by telephone) at a reduced price (at the time of writing) and is preferable to using ordinary Snow Leopard which is quite tricky. You can then run AppleWorks as an emergency measure, provided of course you can obtain a Mac version of it from an independent retailer.
This article about 'Abandoning AppleWorks' is written entirely from the Mac point of view but may be of some help:

You won't be able to open any AppleWorks files on an iPad.
