phantom audio file

I open a project that has 2 vocal files in the audio folder that is within the project folder, as the project opens another vocal file which was not present in the audio folder appears in the audio folder…this is a required file, i thought it was missing when i looked in the folder, however…when I close the project the file disappears from the folder again, the same thing happens with the back up of this project…
does anyone know where this is coming from and where it’s going, I’ve done all the archive stuff…

weird or what!!

cheers, Kevin :slight_smile:
