File extensions for Chapter 4 code samples are incorrect Some of the code samples for the Chapter 4 exercises have an incorrect .xpsa extension. In order to use these files correctly, they should be renamed to .aspx. If the code samples are installed to the default location the following files are located in My DocumentsMicrosoft PressMCPD Self-Paced Training Kit Exam 70-547Chapter 04Lesson 1CS and in My DocumentsMicrosoft PressMCPD Self-Paced Training Kit Exam 70-547Chapter 04Lesson 1VB: Ch04_Intro.xpsa Ch04_MasterPage_Intro.xpsa Ch04_MasterPage_Terms.xpsa Ch04_TreeView_Intro.xpsa Ch04_TreeView_Terms.xpsa The extension .xpsa is incorrect, it should be .aspx. Please use the following directions to rename these files: 1. Using Windows Explorer navigate to the Chapter 4 VB or CS folder containing the invalid code sample files listed above. 2. Select one of the invalid code sample files listed above with the .xpsa file extension. 3. Click on File, then click on Rename. At this time the filename can be edited. 4. Change the filename extension from .xpsa to .aspx then press Enter. 5. Repeat steps 1 through 4 for the remaining code sample files that have the .xpsa file extension.
