Hello Vince53.
Here is my contribution.
Removal of hiberfil.sys (the hibernation file or image of your memory)
You can also execute this simple function with the Command Prompt (Admin) that you can get by right clicking the bottom left corner of the desktop (Windows 8 CP)
If you ever do disk imaging and you find that the file hiberfil.sys adds alot to the size of the image,
which is unnecessary to backup inside of the disk image,
especially if you have no need to hibernate,
you can easily remove it from the system.
>> control panel -> Administrative Tools -> (right click) (select Run as Administrator) Windows Powershell
c:\ powercfg.exe -h off
hiberfil.sys is now removed from your system
to restore hiberfil.sys
again Run as Administrator...
c:\ powercfg.exe -h on
For those unfamiliar with hiberfil.sys,
it exists if your system has hibernation enabled.
It is a system file and cannot be seen unless you go to folder options and unhide hidden files and unhide protected operating system files.
If someone tries the recommendation above to remove hiberfil.sys which can get to several gigabytes,
one can see the file be removed and restored from its default location in the root when the command is executed.
Otherwise, executing the command does not provide any evidence of action unless you go look for it.
cheers
