Bug reports without an attached log file are usually useless.
Did this ever get solved? Same problem here, for years now. I delete files from many FTP servers via a script using .RemoveFiles, but I have one client for whom I cannot delete files via a script, yet I can just fine via the UI. Please advise.
Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.SIZE and MDTM commands.
LIST should work. Can you connect to that server and see the directory listing using WinSCP GUI or any other FTP client, running on the same machine as your code?
