Can't delete hiberfil.sys file from my bootcamp windows7...

There is no Boot Camp administrator, but you do need to be the Windows administrator. Turn hibernation off in Windows and then try to delete the file.

You can't delete it while you are using it, until you reboot Windows you are still using it.

Then I would suggest turning to the Microsoft forums for help.

You're welcome.

You have to run command prompt as an administrator

Pictures show Windows 7 & 8 method. In both, you have to rightclick the command prompt icon for admin slection option.

You can double click embedded Pics to expand them.

Paste this into Cmd Prompt. When complete the file will be gone from C:
powercfg -h off

Info about hibernation:

Hiberfil.sys will appear in the root folder of your hard drive, usually c:\. This file is part of your Windows operating system. It supports the "Hibernate" feature. Some people use this feature to save power while not using the computer. Hibernation takes everything currently in memory and writes it to the file called hyberfil.sys. It is a hidden files.

If you don't use this hibernation, you can get rid of the file:

Go to Control Panel,

click "Power Options".

Select the "Hybernate" tab.

De-select 'Enable Hibernate Support'.

Click the Apply button.

As soon as you restart your computer, the hiberfile.sys file will be gone.

If you delete the file, and do not disable hibernation it will return at the next hibernation.
