I\'m using FtpLib (Python) to download a folder with files from an ftp server. But I want to know the size of the folder before I start downloading it.

Answer 1

After some trial and error I found the solution.

It's based on Alex Thorntons solution but I kept in mind that there could be subfolders. When it's a folder, the ftp.cwd() command succeeds and the function is called recursively.

When the ftp.cwd() command throws an error, it was a file and we can get the file size. The type is set to "I" (images), this forces binary mode since the ftp.size() command is not allowed in ASCII mode.

def get_total_size(self, directory):
    size = 0
    for filename in self.ftp.nlst(directory):
        try:
            self.ftp.cwd(filename)
            size += self.get_total_size(filename)
        except:
            self.ftp.voidcmd('TYPE I')
            size += self.ftp.size(filename)
    return size
