Swap Files

What is a permanent swap file?

IF you don't know the answer to the above question, then chances are Windows is running a lot slower than it should.

When Windows runs out of RAM (main memory) it uses some of your hard disk as "virtual" memory. The area used is known as the swap file. This swap file can be set up in one of two ways:

A temporary swap file, where the computer uses sections of the hard disk as and when it needs to. This method is slow, but compatible with all systems.

A permanent swap file, which has a specified amount of the hard disk (10-20Mb) marked off for Windows use only. This method is compatible with most PC's, but not all. It is however much faster than using a temporary swap file.

In most circumstances, permanent is the most appropriate method to use. Unfortunately, Windows initially installs with a temporary swap file set up.

So, now that you understand what they are, how do you change them?

First defragment your hard disk and make sure you have at least 15Mb of free space for a permanent swap file.

Open the Windows Program Manager and load the Control Panel. Select the Enhanced icon and press the Virtual memory button. The next screen you will will tell you what type of swap file you currently have set up. Take note of all the settings on this screen, you may need them if you have any problems.

To change these settings, press the Change button. The window will expand to show some new swap file settings.

Set the Drive to be the fastest drive in your PC, with the most hard drive space available. This is usually C:. For Type select Permanent and change the New Size to match the Recommended Size. Also, if possible, select the boxes next to Use 32-Bit Disk Access and Use 32-Bit File Access.

When you have finished making the above changes, press the OK button. The computer will ask you if you are sure, select Yes. Then select restart Windows when prompted. Windows should now boot up with greatly improved performance. If there are any problems, or if you receive any error messages, just follow the above procedure again, changing the settings back to how they were originally.
