I will explain how to set up a swap partition on coLinux. It is an important thing to do, especially if you do not give coLinux access to much memory. It will be assumed that you have already installed coLinux and that you are able to run it. * First, we need a file of predetermined size which will be used as our swap partition. The size of this file will determine the size of the swap partition. You can create the file manually, or you can download and unzip one of the premade swap files of various sizes provided by (the filename indicates the size of the unzipped swap file in megabytes).
