Location	File Management

The Load All Files step uses the path to a directory and will output a list of all files found in this directory and any nested directories. The step will not indicate the location the file was pulled from. If the full path to the directory is not entered, the step will begin searching from the C:\Program Files\Decisions\Decisions Server for the directory.
