What is a QAT File Type?
When you make changes to the Microsoft Word tape, it does not change the tapes in other Microsoft Office Suite applications. Change each individual program in order to make changes. QAT files are named according to the program in which they are modified, e.g. the Microsoft Excel QAT file is named Excel.qat.
To make changes, select the Microsoft Office button, click the Word Options button, and click Customize. You can also click on the d'bar just to the right; tools and select Customize the d'bar; tools d' quick access.... A third, more direct method would be to modify the XML code directly in the QAT file.
The QAT file has been replaced by the OFFICEUI file in Microsoft Office 2010. To transfer your customizations to Office 2010 rename the file to QAT ", extension to OFFICEUI ", and place the file in the appropriate program directory.
