What is an ALD file?
An ALD file is a data file used by Microsoft Dynamics AX, a discontinued enterprise resource planning (ERP) system. It contains text strings that appear throughout the Dynamics AX user interface, including form labels, field names, menu items, help text, and system messages. Instead of hard-coding text directly into the application, Dynamics AX uses ALD label files to manage interface text in a centralized and structured way.
More Information
Developers and system administrators typically manage label data when customizing the interface, creating new modules, or translating the system for different regions. ALD files are saved in a proprietary binary format and work together with corresponding .ALI Index files, which help the system quickly locate and retrieve label entries.
Each ALD file contains label entries for a specific language, which allows Dynamics AX to support multilingual environments by loading the appropriate label file based on the user's language settings. For example, one ALD file may store English labels, while another stores German or French equivalents.
NOTE: ALD files are typically stored within the Dynamics AX application directory. An example directory:
C:\Program Files\Microsoft Dynamics AX\[version]\Application\Appl\Standard (Depends on the installed version)
How to open an ALD file
You can open ALD files with Microsoft Dynamics AX. The built-in label editor and development tools provided in Dynamics AX allow you to view, create, and modify label entries. However, Microsoft no longer develops Dynamics AX.
