I've been using AudioMulch for a loooong time so I have 1,000's of .amh files.
Thing is, over the years, I've had my audio libraries on different drives (D:, E:, etc) as I've worked on different audio workstations. Many of the folder names have also changed as I've reorganized my stuff (my 'drums' folder has been parsed out into 'kick drums', 'snare drums', etc). The idea of going through each individual .amh file and updating the paths is daunting to say the least.
And yet I still go back to some of those old files to plunder material or re-engineer it into something new.
It would be awesome to have a way of automating the updating of references. Maybe by creating an index file of every .wav on a computer, then an .amh file can reference the index and automatically update the paths? Not sure, just a random idea.
