# Mapping data with cMap

This scenario applies only to Talend Data Management Platform, Talend Big Data Platform, Talend Real-Time Big Data Platform, Talend Data Services Platform, and Talend Data Fabric.

The following scenario creates a three-component Route, in which a cFile component visits a local file directory to copy its contents, performs a transformation using a cMap component, and then sends the files in the input directory to an output cFile component that writes the files in another directory.
