Use the SFTP Upload FileSet action to upload all the files in an existing FileSet.
Upload Options
SFTP connection
Reconnect if disconnected
Source FileSet
Select the FileSet that contains the files that you want to transfer.
Destination Directory
Specify the name of the directory on the SFTP server. You may specify a directory that doesn't exist and it will be created for you. Make sure the directory is a full path (specified from the user's home directory). The SFTP protocol doesn't have the concept of a "current directory" like FTP does.
Options
Upload Mode
Select what should be done if a file already exists on the server with the same name. Select either: Overwrite, Skip, Append, or Resume.
