Question

I can't enable hibernation in Windows 7 because there is not enough room on my C: drive to create the hibernation file. How can I make Windows put the file somewhere else?

Answer 1

You can't, it has to be in the root of the boot drive (the C: drive in your case).

Raymond Chen explained the reasons why in this Windows Confidential article: The File System Paradox.

Hibernation follows a similar pattern. Hibernating the operating system means dumping the entire contents of memory into the hibernation file; restoring from hibernation entails sucking that file back into memory and pretending nothing happened. Again, it's another chicken-and-egg problem: to load the hibernation file, you need the file system driver, but the file system driver is in the hibernation file. If you keep the hibernation file in the root directory of the boot drive, the miniature file system driver can be used instead.
