What is a .a5l file?

The .a5l file extension is associated with Ace Database, a relational database management system developed by Ace Software. These files typically store data tables and relationships within a database project. They are proprietary to the Ace Database application, meaning they are not easily opened or edited by other general-purpose database tools. If you work with Ace Database, you'll encounter .a5l files as the core components of your data structure. Opening them requires the Ace Database software itself.
