Why Can't I Move Windows 10 Hiberfil.sys to Another Volume?

In some PC, hiberfil.sys is unable to move to another volume. Because of Windows system must load the filesystem driver program if it reads the booting files from other places on hard drive. However, hibernation system's filesystem driver program is inside the hiberfil.sys. It can't load outside the system partition. As a result, hiberfil.sys file can't read without loading filesystem driver program. This is why you can't move Windows 10 hiberfil.sys to another volume.
