Process name: Windows paging file
Pagefile.sys is a windows system files, acts as swap file and was designed to improve performance. Windows uses it as RAM in case the application you're running on your computer ends up needing more RAM than you actually have. Usually page file is 1.5 times than your actual physical memory size, it is the recommended minimum size. The maximum size is 3 times than your actual physical memory size. Pagefile.sys is a hidden file. It means that you could see it in windows file manager only if you checked 'Show hidden files and folders' in Folder Options.
Can I delete pagefile.sys? As a system file you canít simply delete it as you would for, say, a file that you yourself created but no longer wanted on your computer. To do so set both initial size and maximum size to zero, or click No paging file (Just right click on the workplace icon - either in start menu or on desktop - and select properties -> advanced -> performance options) then restart your computer. Your computer is no longer using pagefile.sys, and you can delete it now. To recover the pagefile.sys set some values to both initial size and maximum size the same way mentioned above. Microsoft strongly recommends that you do not disable or delete the paging file.

|All comments about pagefile.sys:|
| Many people believe that with no pagefile there will be no paging and everything will remain in RAM. They could not be more wrong. Disabling the pagefile will not prevent paging, it will probably increase it. Paging of executable files, DLLís, etc does not involve the pagefile and will continue as usual. This is inherent in all virtual memory systems and cannot be prevented. The pagefile is designed to store modified data that has not been recently accessed. This makes more RAM available for more important purposes, such as for active applications and file caching.|
Disabling the pagefile unbalances the entire virtual memory system. Modified data must then remain in RAM no matter how infrequently it is accessed. Uninformed users may believe that with 2GB of RAM they have more than enough to accomodate this. In many cases this will not be the case. Even with 4GB of RAM paging may still be necessary with memory intensive applications. With no pagefile this will be limited to paging of executable files, etc., that do not use the pagefile. With fewer options available Windows will be forced to make poorer choices about what should be paged.
Disable the pagefile if you must, but be warned you will probably impair performance. See also: Link Alex
|The paging file is not necessarily a single file; it can be a group of files stored in various locations, across hard disks and partitions. The files are collectively referred to as "the paging file." When thinking about the size of the paging file, the sum of all the files that make up the paging file is the only value you need to keep in mind. See also: Link Elena|
|Its a legitimate system file Abdul|
|It is just a windows system file designed to act as an ram when needed Suleman|
|Actually it wont be of 1.5 times than the physical memory and it is not recommended too. And we are not setting the size dynamically , it was created when we install the new os by rounting itself in root directory manikandan|
