A paging file is a file that is stored on the hard disk and is used by the system to store data that simply cannot fit in RAM.
Actually, virtual memory itself is all the RAM that works with the swap file. All operating systems (Windows XP, Windows Vista, Linux, Mac os) determine the amount of virtual memory themselves. It should be enough. But if you have a lot of programs running on your personal computer at the same time, while a game is also turned on, or even several, then the virtual memory can be increased to reduce the load on the processor. To do this, right-click on "My Computer", then click on the inscription "Properties". You have a window open. Go to the "Advanced" tab and click on "Options". (Windows Seven does not have a "Options" button, so you should click "Advanced system settings.") In the window that appears, go to the "Advanced" tab again, then click the "Change" button. In the new window that appears, you can change the paging file. First you need to select the disk that will be used for the paging file, preferably the one that is least loaded. Attention: do not use a disc with the system! Then put a dot / check mark next to Custom Size. Next, in the "Initial size" field, set the smallest value for the paging file, and in the "Maximum size" field - the largest value for the paging file. It is recommended to set the minimum value one and a half times more than the entire RAM, and the maximum value is recommended to set 5000-6000 MB. To get rid of the paging file on other local drives, you need to select a drive from the list and check the box next to the "No paging file" message. Now click "OK" so that all operations on the personal computer are completely saved.
