Microsoft Word 2007is capable of working with documents in three file formats

by Mark Matthews



Microsoft Word 2007 is capable of working with documents in three file formats. The native format uses the file extension ".docx". Files saved in this format can use the full range of features found in Word 2007, with the exception of macros. Any Word 2007 document which contains macros must be saved in a separate file format using the file extension ".docm".

In addition to these two native formats, Word 2007 is also capable of both opening and creating documents using the ".doc" file extension, the file extension found in previous versions of Word. Word 2007 files saved with this file extension will not have access to the full range of features found with in Word 2007. Features which have been introduced in 2007, such as Themes, will not be available in documents saved with the file extension ".doc".

Whenever a new Word 2007 document is saved for the first-time these three file format options are available in a drop-down menu labelled "Save As Type". Unless you choose a different option, new documents will be saved with the file extension ".docx". However, if you’re sharing the document with a person using an older version of Word, you can save it in a backward compatible format, using the file extension ".doc".

what about the ".docm" format? Well, when you open a document containing a macro, by default, Word displays a security warning notifying you that macros have been disabled. If you want to, you can then click on Options and enable the content.

Whenever you open a file created in a previous version of Microsoft Word, Word 2007 doesn’t automatically convert the file to its new format. For convenience, it leaves it in the ".doc" format and goes into a special working mode called "Compatibility Mode". (It even displays the words "Compatibility Mode" in brackets next to the document title.)

As long as the file remains in compatibility mode, you can still continue working on it, making changes to the document and saving those changes. However, certain new 2007 features, such as Themes, will not be available. If you place the mouse over the Themes group of the Page Layout Tab, you will see a tool tip saying: "This document has been opened in compatibility mode. To use this feature convert your document to a new file format. Click on the Office button and then click convert." If you do as the message invites you to, "Compatibility Mode" disappears from the title bar and when we save the file Word changes the file extension and the document will then have been converted to the Word 2007 format.

If you work in an environment where both Word 2007 and older versions are in use, then Microsoft may have provided another solution. You have the option of installing an update called the Office Compatibility Pack. This makes it possible for previous versions of all the Microsoft Office packages to open the new Office 2007 file formats.
