Windows 10: What is pagefile.sys and can I delete it?

Just that, This file is 6 GB large and I don't have any sense of what it does.

Clear Pagefile on Shutdown


I've been looking into clearing the pagefile, and I found the following steps at a somewhat dated webpage:

1. In the registry editor, navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
2. Set ClearPageFileAtShutdown to the REG_DWORD value of 1.
3. Restart Windows.

I'm just wondering whether those steps are still valid, and, if so, does clearing the pagefile work as advertised?

 

Deleting Hiberfil & Pagefile

Howdy,

So I have a 60gb SSD with Windows 7 and Office on it (all specs are listed <--- under my username). I have a 12gb pagefile and a 9gb hiberfil, is it possible to delete those or make it so that hiberfil at the very least is no longer created? I just want a little free space on there for future use.

Thoughts?

 

Deleting Hiberfil & Pagefile

Pagefile size depends on RAM, just find optimal value and stick to that.

If you use SSD and want more free space then disable System Restore. It is far more efficient than disabling hiberfil

After disabling hibernation hiberfil.sys gets deleted automatically.
