If you create a document using Microsoft Office 2007 can it be opened and edited by someone using an earlier version of Office?

If the document was created using Microsoft Office 2007 then it will have a file extension similar to the earlier versions but with an x at the end of the file extension. For instance, if the file is created in Word, then the file extension with be .docx and will not be able to open in any earlier versions of Microsoft Office. You can create a document and when saving use the drop down box at the bottom to save it as a Word 97-2003 .doc file. These .doc files are the only files that will work with earlier versions.

For instance: Word 2007 file extension - .docx

Excel 2007 file extension - .xlsx

Powerpoint 2007 extension - .pptx

Word 97 - 2003 extension - .doc

Excel 97 - 2003 extension - .xls

Powerpoint 97-2003 extension - .ppt
