Clear PageFile Sys, Windows Virtual Memory Size

 

In this article we will learn how to clear Pagefile.sys file.

 

What is the Pagefile.sys file

This file is very special and uses Windows to temporarily store data which are exchanged between the RAM  in order to have a larger block of memory, it is known as VIRTUAL MEMORY.

The file name is pagefile.sys and is created at the time of Windows installation on the root drive (usually C: \) where the system boot is located and its attributes are hidden.

This file should normally not be viewable in Windows Explorer, unless you have disabled the "Hide Protected System Files" option.

The file size is typically 1.5 times larger than the system's RAM. (For example, if you have 1GB of RAM, the file should weigh something like 1.5GB, if you have 256MB, the pagefile sys file should weigh something like 384B, and so on, etc.)

Can my system work without a pagefile.sys file?

 

Simple answer

The answer is YES. Yes, if your system has enough RAM to worry about when you are running the maximum number of applications and doing the most tasks on a maximum work day. If you have 2GB or more, you can try to see how your system works.

Now, as a professional recommendation, NO, I DO NOT recommend that you leave the system without any pagefile.sys file, your system may need some extra memory at some point, and not being able to use VIRTUAL memory may cause some type of crash (Freezing) system, so be warned. Many things will stop working if you delete it and many manufacturers create software based on that file exists on the hard drive, and Windows XP does not use the file until you need it so you will not get any benefits by removing it.

Note: In windows 2000, if there is no paging file, you will get a warning window telling you this on every reboot.
