What Is Pagefile.sys? How to Delete Pagefile From Windows

Many elements, either virtual or physical, play an important role in helping your PC work properly. One of those is Pagefile.sys, a key factor in your machine handling larger programs and files.

But it consumes a lot of storage, and it’s surely a concern if you’re running on low storage. So, if you want to know more about this file and know if you can delete it, keep reading the post.

What Is Pagefile.sys?

Pagefile.sys is a paging system file in Windows that helps offload Random Access Memory (RAM) when it runs on low storage. It’s created and operated automatically by the system, and If you have opened many files and apps and the RAM doesn’t have enough storage, then Pagefile.sys will store that.

Let’s understand this in more detail; suppose you have opened an app and kept it open in the background. Then the app will keep consuming RAM on your device so that you can access the app later quickly.

Now, if you open a new heavy app, you’ll need enough storage available in the RAM, so if your machine doesn’t have that storage, it’ll write some data of the closed app in the pagefile.sys.

Later if you open the minimized app, it’ll read data from the Pagefile.sys without using the RAM.

But you should also know that reading files from the Pagefile.sys is slow compared to reading from the RAM, and the process becomes slower if you use Hard Disk Drive (HDD). However, it’s helpful for users who don’t need to close the app fully to open another.

Can You Delete Pagefile.sys?

Pagefile.sys takes up a lot of storage on your computer, so you’ll want to delete the file for obvious reasons. But when you try to delete the file, it says “permission denied,” “File in use,” or other similar messages; this is because Windows marked this file as a “protected system file.”

So, you can’t conventionally delete the file. However, you can follow some extra steps to accomplish the task.

But before you learn the process of deleting and applying it, you should know a few things.

When your RAM runs out of storage, it helps set aside the overload. If it’s unavailable and you use the full RAM, your machine will lag, and even it may crash.

So, if you don’t need to use the RAM fully, you can delete this file to free up storage from your hard drive.

The size of this file depends on your computer’s resources and the RAM it has. But moving it to an external hard drive won’t be a bad option as it won’t take much of your computer’s storage and will also save the data. It’s better to move the file than delete it.
