If you upload a file with STOR and then subsequently try to LIST then the program goes into an infinite loop (freeze). Downloads (RETR)don't show this behavior.

There are supposedly 400+ variations. Only vsftpd-like list responses are being parsed reliably right now.

Don't actually work

When sending over the data socket (uploading) the SendComplete event is raised before the TCP send is actually completed.

listing = listing + "UP" + Format(Directory(i).Permissions, "000") + ","

gives me an error

(This is not an array, but you use it as one)

I think you need to close the DataBuffer when the TransferComplete Fires; otherwise you cannot call store again on the same file without some problems.

Sub TransferComplete(UserAborted As Boolean)
#pragma Unused UserAborted
Me.CloseData()
DataBuffer.Close
DoResponse(226, "Transfer complete.")
End Sub

In Xojo2019r2 the event signature of TCPSocket.Error was changed to include the error as a RuntimeException parameter. This broke all uses of AddHandler TCPSocket.Error.

The AUTH verb allows the client to initiate SSL/TLS negotiation on an existing clear-text socket.

However, when the FTP.Server class is used with a ServerSocket, the negotiation fails and clients report unexpected/illegal negotiation packets.

FileZilla:

Error: GnuTLS error -19: An unexpected TLS handshake packet was received.

FTPRush:

error:14092072:SSL routines:ssl3_get_server_hello:bad message type

FlashFXP:

SSL error:141A10F4:SSL routines:ossl_statem_client_read_transition:unexpected message

It is not currently possible to queue multiple uploads and downloads, rather each operation must be completed before the next one is queued.

All operations should be queueable.
