Is There Such a Thing as an Unusable Sound?

I'm very staunch believer in that there's no such thing as an unusable sound. It's just a sound that's not right for the project you're working on right now. So I have kind of three features, the backed up original source, the clean top entailed kind of virgin state and then any designing that I've done to it. But I only put the ladder to actually in my library. The rest is just on a drive in a folder with the date that I recorded it so I can go get it if I need it.
