## 2.4. The Directory Structure of ANSYS CFX

In this documentation, `<CFXROOT>` refers to the path to your installation of ANSYS CFX, for example C:\Program Files\ANSYS Inc\V182\CFX on Windows. The path to `<CFXROOT>` is release-specific to enable you to have more than one release of ANSYS CFX installed.

Some of the important directories immediately under `<CFXROOT>` are:

`bin` | Contains executable programs for starting ANSYS CFX software components.
`config` | Contains the host definition file for ANSYS CFX software.
`etc` | Contains various data files common to all supported system types.
`examples` | Contains files that will help you work through the ANSYS CFX tutorials. There are sample meshes, CAD files, session files, CFX Expression Language files, User Fortran examples, and example C source code files.
`include` | Contains header files used by parts of the ANSYS CFX software.
`lib` | Contains libraries needed to relink the CFX-Solver for user-defined mesh import or mesh export.
`tools` | Contains software tools such as `cygwin`, `perl`, and `qt`.
