    <sca:service name="GreetingService" promote="GreetingService">
        <camel:binding.file>
            <camel:directory>target/input</camel:directory>
            <camel:fileName>test.txt</camel:fileName>
            <camel:consume>
               <camel:initialDelay>50</camel:initialDelay>
               <camel:delete>true</camel:delete>
            </camel:consume>
        </camel:binding.file>
    </sca:service>
</sca:composite>

• fileExist

• tempPrefix

• tempFileName

For detailed description of these parameters please refer camel-file documentation

<sca:composite name="camel-binding" targetNamespace="urn:switchyard-quickstart:camel-binding:0.1.0">
    <sca:reference name="GreetingService" promote="camel-binding/GreetingService" multiplicity="1..1">
        <camel:binding.file>
            <camel:directory>target/output</camel:directory>
            <camel:autoCreate>false</camel:autoCreate>
            <camel:produce>
                <camel:fileExist>Override</camel:fileExist>
            </camel:produce>
        <camel:binding.file>
    </sca:reference>
</sca:composite>
