I've tried that…For example we have a document library called Meeting Minutes. Inside Meeting minutes there is this folder structure:
2011 > PQP > PQP-CLUE
All I want to display is the documents in the PQP-CLUE folder and I put this in the CAML Filter for Folders:
<Eq>
<FieldRef Name="FileLeafRef" />
<Value Type="File">PQP-CLUE</Value>
</Eq>
I have Show Folder Tree on Page Load checked and all I see after applying this filter is Meeting Minutes and there are now subfolders available or documents.
I've attached some print screens to help see what I'm talking about.
