TopologiLinux is a free Linux distribution to be run on an existing Microsoft Windows system.

It is based on Slackware and Cooperative Linux (coLinux).

TopologiLinux creates one hard disk image and other related files in a directory "/tlinux*" (where * represents the version number of TopologiLinux) on a chosen drive using Windows.

TopologiLinux creates a hard disk image file on an NTFS or FAT partition.

TopologiLinux uses coLinux to run on Windows; because of the cooperative design of coLinux, it is possible to work on Windows and Linux side by side.
