Windows 10: My C: drive randomly filled up, then went back to normal, trying to figure out what caused it.

I have windows 10 installed on my C: drive. Normally I have about 50gb free on it. Well a few minutes ago I got a message on windows saying its almost full and if I would like it to free up space. I checked and i only had like 6gb free. I went through the c drive to see if i could delete anything. As I was doing that it started to slowly go back to normal, from 6gb back to 50gb free. Does anyone know what would of made it do that? The only thing I was doing was downloading updates for games on steam, which are on my D: drive.
