Some programs (e.g., PTV VISUM) export shapefiles in .zip with file extensions being .SHP, .SHX, .DBX. The main branch of this program seeks file extension .shp (lowercase) in the zip file, thus cannot find shapefiles with uppercase extensions. I have made minor modifications to the code to resolve this issue.
