What is the input type 'mimefile' on ZipLoop?

The Community Nodes:GenericKnimeNodes:Flow:ZipLoop takes a 'mimefile' as input to (for example) identify what files to process from an 'Input Files' node. 

Is there documentation on this? I'm attempting to create output for a ZipLoop node from a Python script...and I'm not sure how to proceed. Is 'mimefile' just a regular MIME object?




from your other post on the subject I believe you have figured out in the meantime that the ZipLoopStart node actually expects a URI Port object as input(s). Or is this a different question/issue?
