4. Music Type
So far, this article assumes that the music folders on a CD won't copy to the hard drive, and that the CD in question is a manufactured one from a particular group or recording company. But what if the CD is user created? By that I mean that the CD is user made, with certain types of music on it from different genres and artists.
If that's the case, there's another issue. Certain players play certain types of music formats. The most popular is MP3 or WAv format; however there are other formats, like those that may only play with Real Player, QuickTime or even iTunes. In this case, you may want to keep track of which formats play in which players. MP3s are fairly universal, but MP4s are usually only playable on iPods and some mobile phones.
If you have this type of CD, the best thing is to get the program from which the music will play. Luckily, Real Player, QuickTime, and iTunes are all free for downloading. If the CD was copied using another form of software like Nero or Roxio, there are free trial versions that you can try. You can also look up any issues that you may have with files that were copied using their program.
5. Music Player
As mentioned above, the type of player may also stop you moving music folders from a CD. Most music players have the option of copying (or ripping) music from a CD and placing it on the hard drive, usually in the music folder. Some players will only play a specific type of music format, like the iPod with MP4s. If using WMP, it will play WAV and MP3 formats, but may have issues with others unless codecs are installed for them.
Sometimes simply installing codecs can work, but again, it could also be an issue with the player itself. Trying different players may work; if using WMP, try using Real Player or the DivX player. Again, both are free for download.
