If I want to take a few Lightroom files from my external drive to edit in PS3 while traveling what are the steps to copy them to a folder on my desktop? I do not want to travel with an external drive. If my goal is to edit them and then end up with jpegs for web after editing, should I transfer as raw, work on the files on my desktop and then convert to jpegs? Lightroom and PS3 are installed on my laptop. All files now are on my mirrored external drives.
