Can I put the hibernate file on a drive other than C:?

My gaming machine has more RAM than C: SSD, so the hibernate file gets quite annoying. Can I move that somehow?

If you can live without Fast Startup and Hibernation, disabling it is the best solution. This will completely remove the hiberfil.sys file, freeing up valuable space on your C: drive equal to roughly 75% of your total RAM.

powercfg.exe /hibernate off

Reboot your PC. The hiberfil.sys file will be gone.
