What is Page File ?


Learn how to configure and increase the Page file on your Windows computer to boost performance. Discover the secret to smoother multitasking and a faster system.

Page file
is the Windows paging (or swapfile used to manage virtual memory. It’s used when a computer has low physical memory (RAM), and it’s a hidden system file located at C:\pagefile.sys by default.

In simple terms, a page file in Windows is like a backup for your computer’s memory (RAM). It helps your computer run smoothly even when you’re using a lot of programs. Imagine you’re working on a big project and have many apps open, like a web browser, a music player, and a game. Your computer’s memory (RAM) is like a table where you can put all your stuff to work on. But sometimes, the table gets too crowded because you have so many things on it. That’s where the page file comes in. It’s like having an extra table next to the main one. When your main table (RAM) gets too full, Windows moves some stuff to the extra table (the page file) so that everything can keep running smoothly. It’s like moving some of your stuff to a storage room when your main room is too cramped.

So, the page file helps your computer handle lots of tasks without slowing down. It’s like having a backup table for your computer’s memory.
