I am using SOAP requests to the Lists web service to get results back from a document library. What I want is the list of documents in a sub-folder. There is a <Folder> option in <QueryOptions>, and I am using that with the sub-folder name (eg. as per below), but I can't seem to make this work.

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<SOAP-ENV:Body>

<m:GetListItems xmlns:m="http://schemas.microsoft.com/sharepoint/soap/">

<m:listName>{my list name here}</m:listName>

<m:queryOptions>

<QueryOptions><Folder>FlashExamples</Folder></QueryOptions>

</m:queryOptions>

</m:GetListItems>

</SOAP-ENV:Body>

</SOAP-ENV:Envelope>

This returns no records, even though I know there are documents in the FlashExamples folder. (Without the query options the list returns exactly what I expect -- a combination of documents and folders, as per my default view.)

My problem is, I don't even really know how to identify folders in a list, otherwise I maybe could use a where clause.   

Can anyone suggest how I might do it?

Thanks
