Enter Custom command
Actually, I get the impression that the only reason Justin was asking
about custom commands was that he got the idea that you had to issue
an AUTH command to get FTPS to work.
Relevant quotes:
Chris Bipes:
The AUTH command is used to initialize a secure
connection to the connected FTP server. If you
require SSL then the AUTH must be issues
before you can logon.
Justin Taylor:
Can anyone recommend an FTP client
(that allows FTP commands) for Windows
that supports SSL?
The salient portion of that inquiry is "supports SSL"; the "allows FTP
commands" seems to be purely in service of the SSL.
Quick terminology note: Though the 'S' in FTPS originally stood for
SSL, you should be aware that SSL is obsolete, in a similar sense that
"AS/400" is obsolete. The successor to SSL is TLS, and you should be
aware of both terms.
So, if you are just trying to get FTPS to work in FileZilla, then you
don't have to bother with custom commands. (Indeed, I'm not even sure
you can make it work using custom commands.) The place to set up FTPS
in FileZilla is the Site Manager. On the right-hand side of that
panel, there are four tabs, the first one being "General". In that
tab, you choose protocol, host, and encryption. The protocol should be
FTP. Your choice for encryption controls how FileZilla attempts to
handshake the TLS with the server. In most cases, leaving it at the
default should work. The first time you connect to an FTPS-enabled
server, you should get a message about an unrecognized certificate. If
you trust it, you'll probably want to check the "always trust" box so
you don't keep getting the message in the future.
Also note that the premise of the inquiry (that FTPS cannot be
achieved using the FTP client that comes with Windows) is not correct.
You absolutely can, though from what I can gather via Googling, it's
not that straightforward. The most promising link I found was this:

Further, note that most command-line or scripting solutions for FTPS
on Windows make use of WinSCP, because that route is just so, so much
easier. The fact that WinSCP is scriptable is one key advantage it has
over FileZilla. For programmers using Windows (whether for plain FTP,
FTPS, or SFTP), that is probably decisive.
