## Introdution

The JCR-FTP Server represents the standard eXo service, operates as an FTP server with an access to a content stored in JCR repositories in the form of nt:file/nt:folder nodes or their successors. The client of an executed Server can be any FTP client. The FTP server is supported by a standard configuration which can be changed as required.
