Hi, I seldomly use Aperture nowadays but it is very large and I would like to move the library to an external drive and still access it using Aperture. The library is the original iPhoto library and is used for iPhoto (hardly ever now) and Aperture. I am currently using Lightroom and use Aperture only as an archive, however the file and folder system is so complicated I am unsure what is in Photos Library and iPhoto Library
