How can I get a response of LIST command executed with CFTPConnection::Command(). I can get the directory listing. But not free space size information.
Windows IIS FTP server gives free space as response of LIST command:
How to check free space in a FTP Server?
It does not look like that the MFC CFTPConnection class has an API to access the response message of the command executed.
Though as the class is just a wrapper around Win32 Wininet functions, you can use InternetGetLastResponseInfo function to retrieve the response right after calling CFTPConnection::Command.
Retrieves the last error description or server response on the thread calling this function.
