Page file is used for transitioning of programs and services in the background...

That being said, win98 you should select LET WINDOWS CONTROL PAGEFILE.

NT / 2K / XP , the page file needs to be 2.2 X your base memory...

(i.e., if you 128mb of memory, page file should be at least 285mb.)

*Note* on 98, page files larger than 512 will sometimes corrupt the system depending on the motherboard, periphreals, bios, etc...

Another name for the page file is "virtual memory".
Another nick-name is the 'swap' file.

When Windows needs more memory than you have available, it moves some data to the page file on your hard drive. "Virtual Memory"
(Swaps data between the hard drive and RAM.)

By default, the size of the page file is dynamic. It can range in size from zero to the total open space on your hard drive.

I follow VERY conservative page file settings.
I am more concerned about system stability over speed.

I usually set up a separate 2GB or larger logical drive and allow Windows to use the drive as it needs for the page file.

Alternately, IF a fixed size page file is desired, I use the following formula:

The larger of 2 times installed RAM, or 1GB minus installed RAM.

My reason for this is simple, the less real memory you have, the more virtual memory you need.

Per benchmark tests, there is a slight performance advantage to having a fixed size page file of 1.5 times installed RAM.
(When was the last time your application was a benchmark?)
The primary advantage of a fixed size page file, is that you minimize fragmentation of both the page file and your system and data files.
(When you run defrag, the page file is not defragged.)

I have never come across any issues with Windows stability and too large of a page file.
There is a problem for Windows 98 and Me if you have more than 511 MB of physical RAM though.
