Check if a file contains tag information
In Media Center you can check to see if a particular file contains embedded tag information.
Select the file -> Go to Action Window -> Click on 'Tag'.
There are 2 methods:
1) Click on the top link that states the media type and file size. It is located to the right of the image and above the play count and rating graphic. This link is a shortcut to the detailed embedded file information
2) Look for the field Format. If it is not visible, click the icon in the upper left corner of the Tag window and select Also Show > Format. The Format field should now be visible in the Tag window. Click on the Format label and the file information will display all the physical tags contained in the file, and read by Media Center.
