### VDD file - Voith Dataset Description file

A VDD file is a file that contains a dataset in plain text. The VDD file contains all dataset variables and dataset values. Unlike a dataset that is always provided in Intel hex format and can only be read by the controller, a VDD file can be opened and read using any editor, e.g. Microsoft Excel.

VDD files always have the extension ".vdd". The file name is always identical to the corresponding software version. For example, the VDD file for software version E300.1-D5.3.0.0.hex is E300.1-D5.3.0.0.vdd and is located in the ALADIN "VDD" subfolder. This folder contains the VDD files for all dataset versions that are provided for transmission controllers of the E300 and E300.1 series.
