What is Pagefile.sys and Where it is used?
The pagefile.sys is something that your Windows operating system creates in your C drive that is used to swap data between the hard drive and the physical memory. It is a special paging file that is used when the physical memory is insufficient to hold the running processes or programs.
By default the pagefile.sys size can be up to 3 times the size of the Main memory. We can also say that pagefile.sys is a file that is used as virtual memory.
Virtual memory is nothing but a storage allocation scheme where the secondary storage is used as the main memory.
The use of virtual memory extends the size of the physical memory (RAM) by using the disk and also provides memory protection because each virtual address is translated to a physical address
The benefits of the pagefile.sys i.e. virtual memory are:
- A large number of processes can be managed in the physical memory.
- The Main memory(RAM) can load processes that are larger than its size.
This paging file.sys is not as efficient as the physical memory however, it can prevent your system from getting crashed. By default, Windows manages the pagefile sys.
Also, many users don’t even know this file exists on their system. This is because it is hidden to avoid tampering with the file.
However, if you are running out of space and need to free up some space then one thing that you can try is managing the pagefile.sys. That is you can either transfer the pagefile.sys to an external drive or resize the limit of pagefile sys.
You can also delete the pagefile.sys but before you do make sure to take a backup of your PC.
