Hello. I have a question about keeping my portable external hard drive as the home folder for all of my photographs in Lightroom 5. I don't have enough space to keep them on my computer. I know that Lightroom makes it easy to keep your pictures on an external hard drive by allowing you to edit pictures and then it transfers the edits to the original file once the hard drive is connected. What about when I'm on the go and don't have my portable hard drive. Can I upload new pictures to the computer and they automatically transfer to the external HD once its connected? Or do I have to manually transfer them to the external and then delete them from my computer? Thanks in advance for your help!
