One of the biggest questions that a buyer has, while purchasing a computer, is how much RAM is needed. A tussle between your money and the amount of RAM is always on. But even if you end up buying a smaller RAM you should not feel bad because of Pagefile.sys that Microsoft has introduced to optimize your memory.

If there is data that your RAM can not store that data is stored in Windows Page File or Pagefile.sys. And because of this, your multitasking experience will improve.

How does the Pagefile.sys works?

When you launch an application, its data gets stored in the Random Access Memory or RAM. And when you close it all the data gets shifted to the harddisk. Your computer does this to speed up the task that you are doing, as reading RAM is way faster than reading HardDisk.

Let’s understand this with a simple example when you launch Chrome, your computer reads its program files from the hard disk and then places them in your RAM as it is faster to read.

But if you go on a spree by opening multiple apps and want to multitask then you will have a shortage of RAM. When your computer feels like it can not store more items in the RAM it stores them on a page in your hard disk called Windows Page File or Pagefile.sys.

Even though Pagefile.sys saves your application on your hard disk since it takes more time for your computer to read hard disk as compared to RAM, when you maximize the application again it will take some extra time to load.

Therefore, the moment you close an application that was stored in RAM, and if the application stored in Pagefile.sys is small enough to fit in the remaining space, it gets transferred to the RAM.

But another fact is since most of the modern computer has abundant RAM, therefore, Pagefile.sys rarely gets used. And even if your computer does not have excess RAM, most of us do not open multiple applications at once as we know that it will slow down our computer.

Because of this, we can say that the Windows Page File or Pagefile.sys is a very useful component for a certain niche of audience and time but it is vital for all.

How to see if my computer has Pagefile.sys?
