  Problem

  How can we use ColdFusion to recursively move files from one folder into another?

  Solution

  ColdFusion's cfdirectory tag allows you to quickly get all the files under a folder. One solution would be to simply list all the files from the source directory and then copy each to the destination. However - you have to ensure that subdirectories exist under the destination directory that matches the source directory.
