Overview
What is an ALI file? An ALI file is a label index file used by Microsoft Dynamics AX, an enterprise resource planning ( ERP ) system. It acts as an index, working together with .ALD files that store the actual text labels used throughout the software interface, to help Dynamics AX quickly locate and retrieve label entries, organized by language. ALI files improve performance by enabling the system to reference large sets of translated interface text efficiently.
More Information Dynamics AX uses ALI files internally to manage multilingual support across forms, menus, reports, and other user interface elements. When ERP developers, system administrators, or IT professionals add or modify labels in ALD files, Dynamics AX updates or regenerates the corresponding ALI index file. This process ensures that users see the correct translation for the selected language.

An ALI file may also be a data file created by Adobe RoboHelp, a software application used to develop help systems and documentation for Windows programs. It contains mappings in plain text that link alias IDs to specific help topics within a RoboHelp project, typically in the ID_MyForm=Form.htm format, which associates a unique identifier with the corresponding HTML help file. ALI files are stored within a RoboHelp project, usually alongside the main project file ( .XPJ ) and other project components.
More Information
RoboHelp uses aliases to integrate with the Windows Context-Sensitive Help API , enabling programs to display the correct help topic based on the user's current action. Developers can reference these alias IDs in their program code, and when a user requests help, the software automatically retrieves the linked help file. This approach enables dynamic, context-sensitive assistance, particularly useful for software developers, technical writers, and support teams managing Windows applications.
How to open an ALI file
You can open ALI files with Adobe RoboHelp . Since ALI files store plain text, you can also open and edit the files with any plain text editor, such as Microsoft Notepad or Apple TextEdit .
