This script is useful when you have changed your project folders to a different
directory and you kept all the inside directory root
Paste the old directory in the 'Old Source' input without the file specification
Ex.: Old Source: c:/user/old_project_dir/
Write the new directory ind the 'New Source' input without the file specification
Ex.: New Source: d:/projects_backup/new_project_dir/
If the overall folder structure is the same, all the Read Nodes will be
automatically re-linked to your files.
