I can't get audio or video files into iTunes from my computer. Please help!

Question

Using Windows 7: My wife and I have seperate iTune accounts in our respective computer profiles.  In my profile and iTune account, everything works fine.  In my wife's account, she's always being asked to sign into iTunes as an administrator. Also, her account will not allow her to transfer music or video files into iTunes by drag and drop.  If I click on "Add File to Library" or "Add Folder To Library", It will add the file but double it in the process so there are two of everything.  And to make matters worse, when iTunes open in her profile, it changes the color of the Windows theme.  Someone PLEASE help me. Thank you.

Answer 1

Am I correct in saying that the file is on your computer? Is it in a format that iTunes recognises?
If so, open iTunes, click on the small icon in the top left of the iTunes window and select Add File to Library. Navigate to the folder where the file is located and select it, click on Open. The song is now in your Library, but don't forget that the song's title, artist etc. will reflect the information within the file. So if the file did not have a song title or artist, it will appear in your iTunes as something like "Track 01", by "Unknown Artist".
