For Example: .doc, .docx are both MS Word files. Doc is version 97-2003 and docx is 2007-2010. In Word you can save a document with several different file types. If you have 2010 at home and bring a file to school – it won’t open in our 2007 version unless it has a “patch” installed or you saved it as a different file type.
Rich Text File – save a document that anoyone can open and edit even if the don’t have the Word program on their computer or the same version. Advance formatting features are not saved.
