A number of utilities are available on the the TUFLOW website (http://www.tuflow.com/Downloads_Utilities.htm Download TUFLOW utilities]). Many of the utilities are DOS executables and run without a graphical user interface, like the TUFLOW engine itself. There are also some excel macros and the MapInfo tools, which are MapBasic applications designed for MapInfo.
These utilities are described individually in the page linked below.
