Description of the Article
This is a MDI FTP client application that can explore FTP server. This takes connection information and populates folder and files in treeview and listview respectively. This application is developed and tested with Microsoft NT 5.0,IBM AIX and Sun Solaris 5.6 FTP services. Multiple connections can be opened in different child windows.
This application expects SYST FTP command to be implemented by FTP Server. To display folder and file information, I need to parse the output of LIST command from the FTP server, for this I need to know the FTP Server OS type. Because the output of LIST command is different for different OS. Binary mode of file transfer is not implemented yet.
