What is a .abl file?

AppleWorks Database files, often denoted by the .abl extension, were a core component of the integrated AppleWorks productivity suite. This format allowed users to create and manage structured data, similar to a spreadsheet but with more database-specific features like record management and reporting. While AppleWorks has been discontinued, these files still represent a significant amount of historical data for users who relied on the suite for personal or business organization before the advent of more modern office applications. Opening these files often requires specific older software or conversion tools.
