.ZDF File

The file with zdf extension is a common file that contains only the boundary grid information for each zone. This makes for a smaller file for transporting between machines and also makes access quicker.

Common files use a flexible binary direct access file architecture. This allows grid data for multizone structured grids and their associated boundary condition data to be stored in the same file. It also supports overlapping grids and unstructured grids.

A Zone Definition File (ZDF) is a formatted ascii file from the McDonnell Douglas surface grid generator ZONI3G.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .zdf file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
