I went looking for a certain event to back it up onto another drive. The only thing I find is the entire Aperture library (everything is separated within Aperture by project of course) I like the simplicity of sticking in the SD card, having the app open up, and importing on the fly. This is how I did it with Lightroom and it works just as well with Aperture. I'm new to Aperture so this fact of not locating the project folder all by itself in the Finder was a bit disconcerting. I'm hoping that it is a simple import setting. I don't want to have to copy files to a folder and then import into Aperture as obviously that represents an additional step. iMovie does put the files into their own folder that can then be found in the Finder.
