Lost want files! Help!

I mixing a couple songs for my punk band. I when I open a song, there are still frames in the tracks with my edits in them, but no wav form. I checked the pool, and it’s the same thing. The tracks & edits are there, but no audio information. The only thing I can think of, was that I had to clean up my hard drive & transferred some files from my desktop to an external hard drive recently. How do I recover these tracks?! Help please!

You have two options: 1. either move the corresponding files from the external hard drive back to their original location, or 2. don’t ignore the “missing files” warning which appears upon opening your project and navigate Cubase to the new location.
