When the first SSD's started shipping with new computers the cost meant that many manufactureres/constructors were using quite small SSD's to put the OS on and then installing a second HDD (usually a 1TB one) for everything else.
Great idea? In theory? Great start up speed and the OS flies along. However M$'s OS's have always had areas of flab, poor programming(?) and wastage.
Many like me, who bought machines 2-3 years ago had 64Gb (or less) SSD'd in their machines with the OS on. In my case Win7 64bit Home Premium. Over the subsequent usage and despite constant management of my machine for deleting rubbish I've found that the SSD has slowly filled up. I know I'm not alone because there's an industry grown up of hardware, software and advice on how to ghost your drive on to a bigger one. Today most machines ship with a minimum of 120 Gb SSD for the OS.
A useful utility to find "bloat" and unwanted files is TreeSize. Google for a free version (there is a payware upgrade with more features) and you can download this excellent utility. "TreeSize Free" is a hard disk space manager. It presents your folders in "explorer style" but shows you the size of everything.
If you're having a problem it's well worth installing this as a first step to see where your space is being used.
Having prepared to ghost my drive I was doing some final checks and I noticed a really "Standout" system file. It was a staggering 6Gb!!!!
It was called hiberfil.sys . A quick Google What is hyberfil.sys in Windows 7? sent me straight to "How to Geek's" page. It turns out this massive file is part of the OS that controls the Hibernate function in the Start/Stop drop down menu!!!
Now you may use Hibernate? I never do. Why then is there 6Gb of data cluttering up my SSD?
The good news is that How to Geek tells you how to disable Hibernate in your Start/Stop menu. The even better news is that having done so the hiberfil.sys file disappears as if by magic
I'm still going for the larger SSD ghosting. I'll still use the larger SSD for the OS only. The old one is just begging to be used for a few Mini Routes methinks?
Hope this is useful to someone out there.
