Using notepad or another text editor, open your SYSTEM.INI file from your Windows directory.

Find the section starting with [vcache], and add the following two lines, or modify them if they already exist.

MinFileCache=0
MaxFileCache=4096

These values set the amount of memory in kilobytes to be used for disk caching, if you have more the 16Mb of RAM you may want to increase the MaxFileCache size, to about 25% of your total RAM (i.e. if you have 128Mb use "MaxFileCache=32768")

Restart Windows for the change to take effect.

Note: If you are receiving an error like "Error: An I/O subsystem driver failed to load" try increasing the maximum size to 6144.
