# Dropping and linking the components

## About this task

This use case uses two cFile components, one as the message sender and the other as the receiver, a cSplitter component to split the source message into sub-messages, a cSetHeader component to rename each sub-message, and a cProcessor component to display the file name of each message routed to the receiver.
