This tip is meant for people who donot use Hibernate feature at all.To those who never heard of hibernation.
let me tell few words about this feature.Hibernation is a feature which stores all the contents of the ram into our harddisk before the system is shutdown so that the user can resume the work from where he stopped.To do this this feature takes good chunk of memory to store all the contents in the Ram .Windows users coin this feature as Hibernate while mac users coin it as Safesleep . This feature is also found in latest microsoft shipment i.e win7which takes hdd space in gb.Inorder to free that space we have to delete a file called Hiberfil.sys .Deletin g dis file is nothing but disabling hibernate feature .To do this type cmd in search box now right click on it and choose the option Run as administrator .
Now type the following command powercfg.exe -h off .Now type exit and restart ur computer.
