I have a blend file that is supposed to be packed with a few wav audio files, but it seems the author forgot to pack them, and I don't have the files, if I try the option File>External Data>Pack into blend file blender shows the error:
Unable to pack file, source path '//long path/something.wav' not found
I've found the library where those files were originally downloaded, and downloaded the required files, now I want to edit the information in the blend file so that blender can find those files.
