D5 render took up all available disk space

While doing a small project, I ran into a very unpleasant situation. D5 gobbled up all the available space on drive C! It’s just fucked up! I can’t even save the project! I deleted everything I could and freed up 40 gigabytes, but 30 minutes have passed and the disk is full again! How to deal with this and why is this happening?

Hi mate, did you install D5 in drive C? or did you import some models in big sizes? can you change the drive to install and try again?

Occupying 40GB is very strange if you are sure your operation is correct, please tell us and we can schedule a remote assistance.
