Question
Diskeeper does not defragment hiberfil.sys?
Answer
Hiberfil.sys is the file where Windows saves memory data when the system hibernates. This file cannot be moved at all. You can either ignore it, or disable Hibernate Mode, which will delete the file. To disable Hibernation Mode, go to Control Panel, Power Options. In the System Standby box at the bottom of the window, select Never, then click Apply.
