In the left pane, expand Transfer.
Select ASCII Types. A list of the file types that are transferred in ASCII mode will be displayed. If the file type you want to transfer is not displayed, select OK and proceed to step seven. If it is displayed continue with step four.
Select the extension of the file you want to transfer in binary mode.
Select Remove.

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.
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 choosing File > Transfer Type from the menu. Once CuteFTP is restarted, it reverts to the transfer type set under Global Options.
