I need to log in to an FTP server and upload files. For example, I know things like the MPUT and BIN commands. But there is one problem: after logging in to FTP, I want to first determine whether a folder exists. I know that in DOS there are commands that can directly check locally. For example, if not exist can check whether a folder exists, but after I log in to FTP, writing it like that doesn't work.
Thanks!
