Microsoft Windows Media ASF Viewer 9 Series is a tool for inspecting the contents of files such as .asf, .wma, .wmv, and .mp3 files. Examples of the objects within these files include header, data property, and codec objects.
You cannot use ASF Viewer to edit the file or the metadata within the file; it is simply a tool that you can use to view the contents of the file structure. ASF Viewer has a graphic user interface, but you can also run ASF Viewer in batch mode from the command prompt.
