i have txt file content

thehouse1.jpg, thehouse2.jpg,thehouse3.jpg,.....,thehousename.jpg

I did a script that reads the txt content, then selects the folders "Source Folder" and "New Folder" 

Then it will copy all files named in txt file from "Source Folder" to "New Folder"

Anyone help me with the code, thank you and receive my gratitude
