Steve,
You need to do the following in order to get file and folder names from File/FTP adapter.
1. fileAdapterInboundHeader.wsdl, FTPAdapterInboundHeader.wsdl files does have header structure for file and FTP adapter respectively. These files have the following Header definition:
<types>
<schema attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/file/"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:FILEAPP="http://xmlns.oracle.com/pcbpel/adapter/file/">
<element name="InboundFileHeaderType">
<complexType>
<sequence>
<element name="fileName" type="string"/>
<element name="directory" type="string"/>
</sequence>
</complexType>
</element>
</schema>
</types>
<!-- Header Message -->
<message name="InboundHeader_msg">
<part element="tns:InboundFileHeaderType" name="inboundHeader"/>
</message>
2. You need to create a variable of message type InboundHeader_msg.
     2.a. Open variable creation dialog box. Choose Message Type as type and open the Type Chooser.
     2.b. Expend Message Type and then expend Project WSDL Files.
     2.c. You will see fileAdapterInboundHeader.wsdl/ftpAdapterInboundHeader.wsdl there.
     2.d. Expend the wsdl file and select message type InboundHeader_msg.
3. Now you have your header variable, double click on Receive activity and go to Adapter tab.
4. Select header variable you have created using above steps as Header Variable.
5. Add an assign activity to get fileName and directory from the header variable you have created.
6. Your header variable will be populated while adapter reads the file.
