Renaming a File to File without Mapping

Question

Hi All,
I am having a scenario where there is a text file transfer without any conversion i.e. basically a file to file scenario with no mapping. The only requirement is to rename source file which has .csv extn to .dat. For instance if the sender file is XYZ.csv, the file at the receiver side should be XYZ.dat.
As there is no mapping, I cannot use Dynamic Configuration UDF in mapping. One other option is to write an adapter module which seems too bulky for this small requirement. So as of now I am looking at any option which I can use without having to create IR objects or do text ->XML -> text conversion.
I hope experts here can help in resolving the current problem and/or give some pointers
Best Regards,

I think you should use the full path address, the same as you used for the folder.
You can also use an adapter module, it is just a couple of lines:
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
                      throws ModuleException{
     try {
        Message msg = (Message) inputModuleData.getPrincipalData();
        Payload payload = msg.getDocument();
        String fileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File","FileName");
        // do something with the filename
        msg.setMessageProperty("http://sap.com/xi/XI/System/File","FileName", fileName);
        inputModuleData.setPrincipalData(msg);
    } catch (Exception e) {
        throw new ModuleException(e);
    return inputModuleData;
