AFP uses a remote volume like a local volume and permits you to
Mount a shared volume from a remote computer
Navigate through the hierarchy for the remote file system
Depending on your privileges, read/write/delete/execute
AFP saves documents and files directly to a remote volume like saving to a local volume. It is used over TCP/IP. (AppleTalk is no longer supported.) It uses URL format to locate servers. For example:
TCP: afp://user:password@server/volume/path
Resources for AFP are located in /System/Library/Filesystems.
AFP can be enabled by turning on Personal File Sharing in the Services pane of Sharing preferences.
