This thread is just a tip for people who don't know this. I just learnt this a minute ago so I wanted to share this out of good will. My C: drive was just filling up every time. I never hibernate my pc so if you don't usually hibernate your pc, follow these steps. First open cmd and you MUST run as administrator. The gif explains it all.
After you open cmd, type "powercfg.exe /hibernate off" Without the ""! When you run this command, you won't be able to hibernate your pc and it will temporarily delete your hibernate files. However, If you want to enable it back, simply type "powercfg.exe /hibernate on"
Hope this helps at least a few people. Thanks!
I am not sure how safe this is! Do it at your own risk!
