Do I need a paging file?
As a matter of fact, the paging file is always installed (by default, the system), and if you still use large and productive programs, it is not advised to turn it off. Some software sometimes does not want to start, the reason for this is the lack of volume of the swap - file (paging file). Also, much depends on the operating system, if you take, for example, Windows XP, then with 512 megabytes of RAM, your swap file should be 2-3 times larger.
Often the question arises whether a swap file is needed if 6 - 16 GB of RAM is installed? Among experts there is an opinion that there is no need to load a hard disk, using its space as a paging file, if you have enough RAM. If you have already stepped over 4 gigabytes of RAM, you do not need the swap file.
