Windows 10 can make your computer use a lot of resources. Sometimes the space provided by physical RAM (Random Access Memory) will be short and make it impossible for you to run existing programs on your computer.
To solve this problem, Microsoft uses a file called pagefile.sys. This is the file that will have the effect of storing any data that RAM cannot do. Although pagefile.sys is not as efficient as RAM, it will limit problems when your computer’s resources run out.

What is pagefile.sys?
We will learn what pagefile.sys is? As I said above, pagefile.sys was created to manage space usage and is located on the C drive. You can only see it when you turn on the feature to show hidden files on the computer.
Pagefile.sys is a page file, and it is extremely popular for use in virtual memory. Normally, Windows stores files, software, and other data on your RAM because it reads faster than on the hard drive.
For example, when you open the Google Chrome web browser, the file in Google Chrome will be read in the hard drive and transferred to RAM. That way, the computer uses copies in RAM instead of reading the same file over and over from your hard drive.
Although it takes more time to write data to the hard drive and read it back than RAM, RAM is just a backup memory – the data stored on RAM is lost as soon as you restart the computer that important files are always saved on the hard drive so that they are never lost and the program will not crash.
So what is the role of pagefile.sys on Windows? This is the file that Windows will monitor your computer when handling many requests on memory. If there are data that you don’t use, Windows will move them into the page file.
