The Synchronize FTP action does not have an option for the user to select the transfer type for uploading, or downloading a file in Binary or Ascii (

This being the case, in order to overcome the limitation, depending on the files that you wish to sync, the 'Download or Upload file to FTP' Action can be used to configure the desired transfer type, right before the 'Sync FTP' Action.

The transfer type will be kept the same for the 'Sync FTP' Action and the files will be down/uploaded correctly.

This is a workaround used in such cases.
