Hi Emily
If you want something with the visual style of Dynamo but possibly more robust & flexible for this kind of thing, I suggest taking a look at Pentaho http://community.pentaho.com/projects/data-integration/
Most of the ‘nodes’ relate to data transformations, but also includes various file nodes https://help.pentaho.com/Documentation/5.1/0L0/0Y0/0L0/040
It is a fantastic tool if you work with databases and the community edition is free.
