Auto is the default transfer type, and sends files in the mode specified for each file's extension. All extensions are sent in binary mode unless they are listed in Global Options > Transfer Settings > ASCII Types.
(CuteFTP Professional Only) SSH2 servers do not support ASCII transfers (see http://www.ssh.com/tech/archive/secsh.cfm). CuteFTP Professional adjusts for this by automatically stripping line feeds prior to uploads and restores them during downloads (prior to the file getting written to disk).
You can specify the transfer type for a particular site in your Site Manager under its Site Properties > Type tab.
You can change the transfer type for a single CuteFTP session by clicking on File > Transfer Type in the main menu bar. Once CuteFTP is restarted, it will revert to the transfer type set under Global Options.
