Unfortunately FTP doesn't have a command to list just folders so parsing the results you get from ftp.dir() would be 'best'.
If the FTP server supports the MLSD command, then please check that answer for a couple of useful classes (FTPDirectory and FTPTree).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
