CIFS (Common Internet File System) Access - Allows access to share files via the CIFS protocol. The access control for CIFS is set as share folder-based. This means that a user must enter a valid account and password for accessing the share, and users can only access the shares to which they have been granted access rights (Read Only or Full Access). CIFS is the recommended file sharing protocol for Windows platform, and allows users to access shares through My Network Places. Mac OS X or later also supports the CIFS protocol support.
FTP (File Transfer Protocol) Access - Allows access to share files via the FTP protocol. Access control rights for the FTP protocol are the same as the CIFS protocol for each share folder. The FTP protocol is a platform-independent file sharing protocol, so the user can use any FTP client program to access shares.
NFS (Network File System) Access - Allows access to share files via the NFS protocol. NFS protocol access is controlled by a set of accepted IP addresses for each share folder. NFS is recommended for users of UNIX and similar systems.
The AFP (Apple Filing Protocol) is a network protocol that offers file services for Mac OS X and the original Mac OS. AFP is one of several file sharing protocols that support mounting remote file-systems on the local machine.
