It is possible to find for which process or applications page file is created for
Many processes use the pagefile, so you can't really do that.
Everything that gets done on a computer, gets done IN the RAM.
When the RAM fills up, Windows uses some space on the much, much slower SSD or hard drive, for the overflow. The extra space Windows uses is called a pagefile.
If you have NO pagefile, then Windows will toss out the oldest stuff in the RAM to allow for newer stuff.
If you have System Managed pagefile, then Windows doesn't even try to be smart. It tosses everything in there.
If you have a fixed size pagefile, then Windows will do like it does with the RAM... newer stuff pushes out the oldest stuff in the pagefile.
Analogy...
When a math teacher works on equations he "uses" the chalk board. That's like the RAM.
When the chalk board fills up, he tells the class to look for more equations on some page in the math book. This is like the pagefile.
Using the math books (pagefile), is much slower than just pointing to an equation on the chalk board (RAM), but it still works.
If he didn't have math books (pagefile), he could just keep erasing spots on the chalk board (RAM), to get more room. But this will slow things down. As you can see, using the math books (pagefile), even though they are really slow, makes things faster in the long run.
