Significance of the Page File?

[Sajuuk]

The page file is what your system sets aside as "virtual ram", in the event you need to use more ram (for whatever reason), your system starts using the page file as ram. That's why old computers slowed way the fuck down if you tried to do something tough on them - low ram, moved to page file.

If your ram consumption (say you only use 8 of 12gb while multiboxing) is low you can set your page file to 0. Note that if you do so and you actually need it at one point in time, it will cause the application to crash.

You can turn it off. (Or reduce it to say 4gb if you really don't want to lose it)
