ASF files vs Windows Media Player Library

Recently I downloaded an audio file having the .asf extesion, which turns out to be unsupported by Windows Media Player library, even the latest version of the player included in Windows Vista, altough the player can reproduce it if you open the file directly.

Luckily, internally this .asf file is just a Windows Media Audio encoded file so I just had to replace the .asf extension as .wma for Windows Media Player's library to be able to find and catalog the file. Another plus is that now with the .wma extension I can tag the file appropriately.
