Can I delete a large hyberfil.sys file if it is not on the boot drive?

My 'D' drive once was a boot drive.
Now that C is the boot I am reviewing files on the D drive to see if I can remove the unused files.
This hyberfil.sys file I find on my D drive is about 3.2 gigs in size and its last date modified is April 27 of 2008.

Would it be okay to remove this file?

Just was to be sure the operating system (Windows Vista Ultimate) has no reason to need a hyberfil.sys from a non-boot drive.

Yes, you can delete that file. It is only used for hibernation, and if needed it would be recreated.
