Local Disc C storage issues

[DatSunny]

Hi, 

For some reason i cant add more photos to my lightroom. I have a 1TB storage but it keeps telling me local disc c needs more storage., 

How can i fix this its driving me nuts!

So basically i went to a car show and took around 1200 photos and trying to add them to lightroom to edit and it wont allow me. I have added them in a smaller batch and its working but is there anything i can change to add the whole amount or can it only be done in smaller batches of photos?
