How would I use native FTP proxying on Windows without an FTP client?

Configuring the proxy on Internet Explorer (IE) allows IE to use FTP over HTTP (when folder view is disabled). It does not use native FTP; hence you cannot use the proxy settings. But we can use Windows Explorer to do native FTP proxying.
Please open Windows Explorer (not IE. example: double click on "My Computer") and use the following URL in the address bar:
# Example when authentication is disabled on WSA ftp://USERNAME_FTP%40FTP_SERVER:PASSWORD_FTP@PROXY:PORT
# Example when authentication is enabled on WSA ftp://USERNAME_FTP%40USERNAME_WSA%40FTP_SERVER:PASSWORD_FTP%40PASSWORD_ WSA@PROXY:PORT
Please keep in mind that this is just a workaround, and may not work in all possible cases. This is under the assumption that you are using "Checkpoint" for "Authentication Format". Folder view is not part of IE, it is part of Windows Explorer, which runs outside of IE. The same technique can be used to curl native FTP traffic through a proxy.
