The ad3 file extension is related to ADHOC, software developed and used by the Interferometric Group of Marseille's Observatory to reduce the 3D data coming from Photon Counting or CCD observations.

It contains also general 2D modules useful for simple imagery. It is commonly used to reduce CIGALE, TIGER and PYTHEAS observations.

This ad3 file type entry was marked as obsolete and no longer supported file format.

This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

Help 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 .ad3 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.
