I am reorganizing a folder of generated songs that has become difficult to maintain. Some exports have a faint metallic texture but I also want to remember exactly what came out of each session. Keeping untouched source files seems sensible. The difficult part is deciding what belongs beside them when I make a more comfortable listening copy. I came across sunofix while looking at possible cleanup approaches. I have not processed this collection yet so I am asking about the filing policy before choosing a tool. Would you give listening copies their own folder? I can note the original creation date but I am less sure how much processing detail is useful months later. A short sidecar note might be enough. Disk capacity is not my immediate concern. How do you label these copies so their history stays clear?
