If you need to run the utilities on multiple files/folders, here are some commands that will help you:
type the following at the command prompt:
for %f in (*.shp) do shptree %f
or to run recursively (throughout all subfolders):
for /R %f in (*.shp) do shptree %f
find /path/to/data -name "*.shp" -exec shptree {} \;
