Don’t know what the pagefile.sys file is good for and you can’t delete it? Learn more about this system file in this tutorial and why you shouldn’t delete it.
What is pagefile.sys?
Pagefile.sys is a file (system file) created and used by system (XP,Windows7, Windows 8) as ‘virtual’ memory and it is saved on hard drive. When physical RAM is fully used and there is need for more physical RAM, any data loaded in RAM and not in immediate use, can be swapped to the page file and thus free physical RAM for immediate use. The swapped data can be transferred back into physical RAM if needed at any time. Windows doesn’t work well without a page file.
Virtual memory is usually at least as large as installed physical RAM. But recommended size for a Page File is 1.5 to 2 times the installed physical RAM. so,Pagefile.sys can be quite big in size. Again, an unnecessarily huge Page file will increase boot time of the system. So, making the Page File too large will not necessarily improve performance.
Deleting Page File is not recommended. But if the size of the Page File is so large, that it increases system boot time or you need some urgent disk space, you may need to delete the Page File.
Follow these steps carefully to delete pagefile.sys file.
