The Server Message Block (SMB) protocol (also called CIFS), is a file and printer sharing protocol which serves as the basis for Microsoft's Distributed File System implementation. Every year, more and more networks utilize the SMB protocol for its advantages over other alternatives.

Contrary to FTP and HTTP, SMB allows not only copying an entire file, but also grants access to files over the network. File editing, for example, can be executed over SMB, without changing its location.

Furthermore, SMB version 3 and above provides enhanced security by supporting end-to-end encryption.

Another alternative, NFS, is also a file sharing protocol similar to SMB. However, NFS is only native to the Linux world, whilst using it on a Windows computer requires installing a patch. SMB scores over NFS as it is a native solution for Windows, Linux and Macintosh.
