Q: Have two albums in iTunes that say can't find file location but they are on iPod nano and will play on nano but not in iTunes

Hello, FayAnnR. 

Thank you for visiting Apple Support Communities. 

Here is an article that I would recommend going through when iTunes indicates that a file can not be located.

If the media was purchased from iTunes, I would recommend deleting the missing media and either transfer purchased from your iPod or download them again via the third article below.
