How to determine which Aperature Library is the original?
I purchased an Imac a couple of years ago and switched to Aperature to help eliminate duplicates. I spent time bringing them in a little at a time as not to duplicate. I have moved what I thought was the master copy to an external drive so that it would not take up all the space. I show eight copies of Aperature when I click option & then Aperature. Please help me determine which is the main copy as they all have different version and original numbers. I am so confused and was just trying to break it down so that I could manage it in even years at a time so that I could organize faces. Not even really sure what version means as opposed to original. I hope with some guidence I can finally get this right. Thank you in advance if you understand where I am coming from
