Need help iWorks?

I have several .doc files ect saved from my windows and when I open from finder it uses the standard text editor is there a way to set iworks to automatically open these files by default rather than the leopard text editor. I can open iworks the open the file but thats seems a waste of time if I could click the document and iworks pages opens it instead. Any help if not possible just let me know. I am sure some guru here has an answer for me

Thanks in advance
