I know why MEDIA OFFLINE but how to I get it to tell me which file is missing?

Hello all,

I know I need to save a new whateverythingamajig because my media is offline due to losing the direct passage it first found its media. But my premiere elements 15 does not say @4075252 is XX file?... sooo... HOW? Please tell me how I can turn on this option i have hundreds of files otherwise. I took my files from one HD to another mac and so its lost all the pathways. Thanks
