Creative MediaSource needs to know where your music is stored before the music information can be displayed in the PC Music Library view
1.Goto the Tools menu bar at the top and select Settings. Next click on the "Media Sniifer"
2.Check "Enable Media Sniffer". Then click "Add Folders" & select the folder in which you store all your music e.g. C:\My Music.
3.Click "apply" and then "ok" to close the settings page.
4.You should be able to see your songs in the PC Music Library. (Note: if you have many songs, it would take some time to register all the music files. Click F5 to refresh the PC Music Library view)"
Although the correct way is for the user to go through the Import Wizard, using the media sniffer would be the fastest and easiest way for users who already have music on the PC, which are likely to be properly tagged.
