The .ad file extension is associated with Anno Designer, a Microsoft Windows program for creating layouts for ANNO video games.
An .ad file stores an Anno Designer project. It is a native project file for the program and preserves the layout being designed for further editing.
The format is tied to Anno Designer on Microsoft Windows rather than being a general-purpose interchange format.
Use Anno Designer on Microsoft Windows to open .ad project files.
An .ad file is a native Anno Designer project file, so it cannot generally be converted to another format while preserving its editable project data.
Open the file in Anno Designer and use any export features provided by the installed version if a non-editable layout or other output is required.

The ad file extension is related to the AppleDouble and used for its encoded files.
AppleDouble leaves the data fork in its original format, allowing it to be edited by normal Unix utilities. The resource fork and Finder information, both propietary and lacking editors under Unix, were combined into a second file.
AppleDouble format should be the primary format when sending a Macintosh document. It makes it possible for a user that can't decode the AppleDouble header to read and use the Data fork of the document.
It also keep the Macintosh specific information in the AppleDouble header, so a user who can decode the AppleDouble header can get the extra information, such as customised icons, which is not essential to the document itself.

The AD file extension is associated with UNIX systems, originally developed at AT&T, and with applications using the X Window System resource mechanism. The file contains application default resource data.
These resources can define default values such as fonts, colors, dimensions, labels, and other application settings. X Toolkit applications can load the values from an application-defaults directory or another resource database and use them when the application starts.
The format is intended for Linux and other UNIX or UNIX-like systems.
An .ad file is a plain-text file. On Linux or another UNIX-like system, it can be viewed and edited with any text editor.
Opening the file in a text editor shows its resource definitions. To use the settings, the file must be placed where the relevant X application looks for application-default resources; the exact location and file naming depend on that application and its installation.
There is no general-purpose conversion format for UNIX application default resource files. The file can be edited as text, or its resource definitions can be copied into another X resource database or configuration file.
Moving the settings to software that does not use X resources normally requires translating them into that software's own configuration format.
