It gets crazy real quick. What I am going to do and I have no clue as to why this eluded me for so long, is bounce out/record a main chunk of the track as a reference and put it in the project folder so I can have a quick listen to what I can expect before I spend the next hour opening and closing each version of a project going, "nah that wasn't the one, must be the next one" etc etc.
The stuff I have named by dates is just silly, I have way too much and I haven't the faintest idea of what they were until I open the DAW project file. This is really time consuming. But then again, you can't really give a track a name until it develops enough. I'd sooner just delete the whole lot than have all the versions with decimal places confusing the hell out of me.
