The DFS (Data File System) is used extensively within the MIKE Powered by DHI software.

It is a binary data file format and it provides a general file format for handling spatially distributed and time dependent data, ranging from measurements of temperature at a single point, to water levels in the North Sea in a 2D grid generated by DHI’s flow models (MIKE 21).

The API in this library allow the user to Open, create and edit all dfs type files: dfs0, dfs1, dfs2, dfs3, dfsu files. It allows creation and modification of static and dynamic items, temporal and spatial axes, their discretizations and corresponding units.

The API is a exported such that it is accessible from C/C++, Pascal/Delphi, Python and any other technology that can consume a C API.

The API methods are documented here:

• dfsio.h
