Windows doesn't even know this as a result of the trick being used - so Lightroom shouldn't care.
Obviously, Lightroom does care, and it will not allow you to ADD photos from a camera card; COPY is the option that Lightroom allows from a camera card.
So, it seems like you need more hard disk space to house these photos.
Like it or not, Lightroom is aware that the files are on a card. And you cannot add images stored that way. If you are that low on space you might consider an external hard drive as an alternative.
Thanks for the input.
Lightroom allows me to copy TO that location on an import but not import FROM it? So I'm allowed to import and end up with stuff there, but not allowed to start with it there. No sense at all in that design. That's downright restrictive and really offers no particular benefit. Hey, Lightroom designers ... change that!
This computer is a powerful ultrabook with a 512 SSD which is as big as reasonably and cost-effective available with the addition of a 256 SDXC card to handle the additional extra capacity I need. Not too many other reasonable options out there. This computer is constantly on the go and the addition of an external drive hanging off of it simply isn't manageable.
Any other tricks out there?
