There are several ways to save documents in Microsoft Word. You can save the active document you are working on, whether it is new or existed previously. You can save all open documents at the same time. And you can save a copy of the active document with a different name or in a different location.
If you have text or formatting you want to reuse in other documents you create, you can save a document as a Word template.
If you share documents with people who use previous versions of Word, and you want to be sure the documents look the same when they're opened in the earlier versions, you can turn off features that are not a part of that version.
Saving documents in other file formats
When you need to share documents with people who use other word processors or who use versions of Word that have a different file format (such as Word 6.0/95 or Word for the Macintosh), you can save documents in other file formats. For example, you can open a document created in WordPerfect, make changes to it in Word, and then save it in either Word or WordPerfect format.
Saving documents for Internet, intranet, or Web use
If you use Word to create Web pages to display in a Web browser, you can save documents in Web page format and publish them to a Web server. You can also save documents to an FTP site on the Internet (you must have an Internet account through an Internet service provider and permission to save documents on the FTP server) or to your company's intranet.
