Tips to Fix *.ITL File Extension Error

Sometimes, when you try insert the iPad or iPhone into your computer, you would find the computer  cannot recognize *.ITL or iTunes file extensions. This problem is confusing but I have found some solutions that will fix this permanently.  Once the user removes the library file, iTunes can restore it by seeking for songs in the Music folder. However, this will not recover the song ratings, playlists, and comments.
