Major One possible solution is to iterate over the file descriptor list and assuming the files in the list have unique names, possibly with file extensions, we can:
1) Check if each file has an extension and write the file to the run folder as "filename" + extension where filename comes from line 146. A user that specified "input" in the filename field when creating the tool, we would write, for example: input.shp, input.dbf and "input".
I'm open to other possible solutions to fix this issue.
