As to the pagefile.sys that is in use by the virtual memory if you have plenty of ram you can turn off or at least reduce the amount set aside:
- click start
- right click my computer
- click properties
- click advanced (tab)
- under performance click settings
- click advanced (tab) under virtual memory click change
here you can change the space available for each drive by choosing the custom button then entering the amount you want
or if ya got lots a ram choose the no paging file either way make sure to click the “set” button when you’re done
When you turn off your computer using hibernate, the operating system needs to store all your current running program states onto hard disk so that programs can resume where they left off when you power up your PC again. To achieve this, the OS need to save all the information into a file called hiberfil.sys. Windows OS (7, vista, XP) usually stores this as a hidden file under your C directory or your main OS partition.
So if you never use hibernate, than its time for you to get your hard drive space back.
[Note: Hibernate mode is not sleep mode. When hibernating your computer completely shuts down, however, under sleep mode your PC is not completely shut down; it still consumes a small amount of power.]
The best way to delete hiberfil.sys or disable hibernate:
- Go to Start menu, type “cmd” open up command prompt
- Type “powercfg.exe -h off” [make sure you are an Administrator]
- Type “exit”
RESTART YOUR PC and you are all set
After restart you should be able to see more free space on your hard drive.
