How to get finder items from a list, automator, including searching through sub-folders

Here is an AppleScript used in an Automator Application via the Run AppleScript action.

• Prompts for an input folder
• Prompts for an output folder
• Prompts for the file containing your 100 filenames.

  Assumption: not full paths to the files, but just filename.ext.

• Reads the filenames from item 3 into a quoted list
• Drills down into the input folder capturing full paths of matching files in item 4.
• Copies (duplicates) matching files to outfolder. Will replace if collision, and copy retains ownership, file permissions, etc.

Launchpad : Other : Automator

• New : Application : Choose
• Utilities Library : Run AppleScript (drag and drop this to the right into larger workflow window).
  • Select boiler plate contents and remove.
  • Copy/paste contents of following AppleScript code into the Run AppleScript action window

    Click the hammer icon

  • Click the right-arrow (Run) icon in the top-right toolbar to run the Automator application interactively as a test
• Automator : File menu : Save... (you can name it copy_files, match_files, etc.) and put it on your Desktop.

  Double-click to run
