Specra (formerly WinDOS) is a GUI Shell for DOS.
Almost Fully Supported in DOSBox 0.72 except compression decompression utility.
Making it work
It works just as it would in dos. You must change to the directory it is installed in to run it. To use the Desktop, unzip the plugin to the same location as installed directory.
