What is a TWF file?

TWF files mostly belong to Casio Pocket Viewer. TWF files mark a range of proprietary data files that come from different companies and serve specific functions.
For some devices, Casio uses TWF as diary or organizer files that hold data such as schedules and personal entries. These files are normally opened with software like Casio Pocket Viewer or Casio Data Manager (Casio provides additional details).
Other TWF files are created as a form of word document by Toshiba. They sometimes include elements similar to drawing data and are viewed with specialized TWF Viewer software, a setup that may intersect with CAD-type drawing exchange (for example, with Bentley MicroStation or in systems like Intergraph SmartPlant Review).
A further variant of the TWF files is used in imaging and 3D projects. In this case, TWF is an ortho image descriptor or a textured wireframe file. Such files are used in applications like TerraExplorer and Trimble RealWorks (SkylineGlobe), where data helps build 3D models.
There is also a use in design, where TWF stands for Turbine Workshop File. These files store information used in turbine design and can be opened with programs like TurboCAD.
