I am trying to build a library of my CD collection using WMP11 so I can use\nMedia Center Edition as my music archive player. I have some 300+ cd's\nalready riped to .wav files using J. River Media player on one of my hard\ndrives. Since I did this before WMP had the ability to rip in wav. All of the\nfile info ( albums,artist,etc...) was lost since J.River stored this info as\na library data base file and I no longer use J. River's player. The files are\nhowever riped into folders by the path artist/album/songs so browsing via\nfolders with wmp11 is productive hower this is not possible in media edition.\nI now have begun to rip new cd's to wav using WMP11. I am a purest and do not\nwant compression. How is WMP11 so call taging the wav file? Is there a way to\npermantly tag the wav files I have already riped not using WMP11? I spend\ndays updating and finding album info and art for all my files thinking WMP11\ntagged the files like it does when I rip a file. Then needed to reinstall my\noperating systems and as you guest all of my beautiful and accurate music\nlibrary vanished. I would of backed-up the library data base file if I knew I\nneeded to and knew what file to back-up. So does WMP11 attach meta data to\nthe wav file when the file is riped but stores meta data in the library data\nbase when you manually update media? Also all of my wav files have one\nfolder.jpegs and three AlbumArt.jpegs but still no album art shows when I\nbrowse folders in WMP11. Why? Will upgrading to Vista improve any of this?
