Hi @dale,

Of course.

@matteo_ledri is this what you need?

```auto
import rhinoscriptsyntax as rs
import System

# hard coded list of files
files = ['C:\\Users\\rhino\\Documents\\__file1.3dm',
    'C:\\Users\\rhino\\Documents\\__file2.3dm',
    'C:\\Users\\rhino\\Documents\\__file3.3dm']

# or all files in a common root directory
files = System.IO.Directory.GetFiles(
    'C:\\Users\\rhino\\Documents\\filestoedit', 
    '*.3dm', 
    System.IO.SearchOption.AllDirectories)

for file in files:
    rs.Command('_-Open ' + file)
    rs.AddBox([(-5,-5,-5), (5,-5,-5), (5,5,-5), (-5,5,-5), (-5,-5,5), (5,-5,5), (5,5,5), (-5,5,5)])
    print "file:{0}".format(file)
    rs.Command('_-Save _Enter')

rs.Command('_-New None')

```
