My Aperture library has become very bloated and a tad unorganised, and I have since moved to Lightroom. I still keep Aperture on my computer (as it'd probably be a waste of money to delete it) but my Aperture library is pretty big, as I imported my iPhoto library when I first got it. In order to start over, would I just need to delete the Aperture Library from my Pictures folder, hold option(?) on opening Aperture and create a new library? Or is there something else I need to do?
