Apple Filing Protocol

The Apple Filing Protocol (AFP) is a network protocol developed by Apple Inc. to facilitate file sharing between Macintosh computers. It was designed to allow seamless file transfer, remote access to files, and network volume mounting primarily on Apple devices. AFP gained prominence with the rise of Mac OS, offering users efficient and reliable means for managing files over a network.

AFP, short for Apple Filing Protocol, originated in the late 1980s as part of Apple’s strategy to streamline file sharing on its Macintosh computers. Initially introduced with the AppleShare software, AFP was integral to the Mac's network environment, enabling users to effortlessly share files and resources across a network. The protocol allows for more than just simple file transfers; it supports various file system functions like permissions, access control, and network volume mounting. Over the years, AFP has evolved to incorporate improvements in security and compatibility. It utilizes port 548 and operates over TCP/IP, making it accessible in modern network environments. AFP is particularly noted for its efficiency and reliability when handling large files and supporting long file names, metadata, and resource forks that are essential in the Mac ecosystem. Although newer protocols like SMB (Server Message Block) and NFS (Network File System) have become more prevalent, AFP remains a crucial part of Apple's legacy networking capabilities.
