Opening pre-Works 6.0 documents is not very simple. AFAIK Microsoft no longer has the old converters available due to security issues: "The Office Converter Packs for Office 97, 2000, and XP have been retired from the Microsoft Download Center due to the discovery of a potential security vulnerability." None of the converters for Word after 2000 work on the real old Works files.
First try THIS
free online converter that may or may not work.
Failing that, the original Word 1997 CD came with all the needed converters on the disk. If I *had* to do that conversion, I would install Word 1997 into an XP Mode VM on Windows 7, convert the documents to Word 1997, and then open those with Word 2010. It would have to be done one at a time, as none of the batch converters are available any more, and I would expect a lot of formatting issues.
