Office 2010 should be open Works 6.0 and later files. The extension wont show on the file format list, so you'll actually need to select "All Files (*.*)" to locate and open your document. Once you've opened your document you may have to do some editing to restore formatting, but it shouldn't be as bad as having to copy and paste the entire contents. Have you tried opening your documents using the "All Files" selection yet?

Unfortunately MS Works has been discontinued, so you're going to have a difficult time finding a copy to install.

Hope this helps.
