What is a .arf file?

The ARF file format is an older, proprietary document format developed by Adobe, primarily used for sharing and archiving electronic documents. It's an early precursor to the more widely known PDF format, designed to capture the layout and content of a document reliably across different systems. While it served its purpose, its limited compatibility and feature set compared to modern formats mean it's rarely encountered or used today.
