In the previous steps, you have used msgtransform to create an output file, changed the VMD file, and then used msgtransform to create a second output file. The next step is to confirm that the two output files are actually different. To do this, use a visual file comparison utility.

	In this example, the two output files are compared using ExamDiff. You can use any comparison program you like. A visual file comparison utility makes it easier to see exactly where changes have occurred.

To compare the changes in the output files:

• Launch ExamDiff. The Compare Window appears.
• In the File 1 and File 2 fields, type the paths of the first and second output files.

Entering the Paths of the Output Files

• Click OK to examine the differences. You will notice that the one small change you made to the sample VMD file is easily found.
