So I was making a video project using Hitfilm 4 Express then I got a notification that the C: Drive is almost full. My PC has a separate storage drive for programs and other stuff. After searching the internet, I found out about the "size;gicantic" thing on the search bar and found these:

I have no Idea what these video.hlm files are but its eating up my SSD storage.
Can someone help me with this?
