The Directory and File Pathnames reader is useful for getting the files paths as an attribute without reading in the data itself. However it currently only takes a folder as the input parameter.
There are situations where the user should be able to pick any combination of files/folders through the Select Multiple Folders/Files parameter interface and the result is one feature per file (not selection) with an attribute containing the full path to the file.
It currently takes 8 transformers to achieve this result.
