I appreciate the detailed response. I’m wondering if it’s possible to obtain information about the folder structure (the entire hierarchy of the directory) with an Elm only approach, without resorting to ports. I know that the relative path is stored in webkitRelativePath attribute inside each file, but I’m not really sure about how to extract that (elm/file supports extracting size, name, etc., but not the path variable). Is there an easy way to solve this that I’m missing? Again, thank you all for your help thus far
