By being closer, the file transfer may involve fewer network connections and less network traffic. This can help to make the file transfer faster. A less busy server ensures a better chance of connecting. Directories and Files Most FTP servers run under the UNIX operating system. UNIX uses hierarchical file storage similar to both PC and Macintosh computers.
Directories can hold both files and subdirectories.
Accessing a specific file involves knowing all of the directories in the path from the top or root directory down to the file. Some directory and file names on an FTP server may look strange or obscure. Often this is due to UNIX, since it allows long directory and file names. A user may also see directories and files that are a part of the server's operating system. UNIX system directories include bin, etc, and usr.
