Windows manages your swapfile automatically by default.
If you want to create a fixed swapfile, then:
Right click on "My computer", go to properties and click the performance tab.
Click on the virtual memory box and select the "Let me specify my own settings".
Now you have to decide how much virtual memory to assign to the system. The less RAM you have, the higher chance you have on using the swapfile.
If you have 64MB of RAM, you probably 'dip' into the swapfile regularly. I use 512MB RAM and rarely need the swapfile.
I suggest you set a minimum which gives you a combined RAM and swapfile of at least 500MB. I set mine to 500MB and with my memory this makes 1012MB. I will probably never go above this figure, so I don't worry about it.
It is better to leave the 'maximum' box at "no maximum". If you feel your system slow down, you can monitor your swapfile in the system monitor to see if you are dipping into it. If so, increase the minimum setting by 200 MB or so.
It all depends on your specs and your usage do play about with it. Remember, whatever value you set as your minimum you will lose as C: drive space.
One more thing.
Run the "sysedit" file and in the system.ini window there is a paragraph titled "[386Enh]". Add at the of this paragraph the line "ConservativeSwapfileUsage=1"
This tells Windows to use all memory before using swapfile space.
