I installed Lightroom with default settings. Apparently one default is to store Draft Edits onto a C: folder. But my C: drive is a relatively small SSD drive and LR fills it up within a few months. Currently I'm using manual functions within LR to move my catalogs/draft edits every time. But I've been looking everywhere within Lightroom menus to change the default from C: to my external drive - No luck so far.
How can I stop LR from saving to the c: default and make it automatically save draft edits and admin photos directly to my selected external drive destination ?
