Yes - I totally agree. It currently uses C:\Users\XXX\AppData\Local\Adobe\Lightroom\Caches\Video . I expected it to use my Lightroom Cache - which I have set to my N drive in preferences. In this day and age of small SSD systems drives that can have disastrous consequences. It also seems to ignore whatever limit is set in the preferences. I have 3G limit set for Video cache and ended up with over 60G buried on my SSD C drive. Too some time to locate what the problem was when my C drive filled up. Win 10 and Photographers Lr/Ps CC.
