Delete remote folders older than X days

Hello,

I have a c# program to find the folders in the FTP server older than X days but I couldn't find an option to delete the folders(non empty).

Can you please help me with the function?

Thanks,
Karthick

To recursively delete a folder, use Session.RemoveFiles.

Thanks mate, appreciate it.

Do we have an option to do sudo through programming as well?

Yes, with some limitations.
