SingleFileZ creates its own paths to reference all the resources of the page in the zip. This prevents any invalid path issues. The URL of the resource is stored as a comment for each entry in the zip though (I'm unsure I'm really answering to your question). If there is a bug in the extraction script, there are some chances you can still unzip the file.
