With this code you can copy all files within a directory with a particular extension to another directory. Actually it will give you a progressive listing of a file with a wildcard and then you can do whatever you want with the file. Extremely simple and straightforward. I dont understand why the other codes are so huge. If you find an error or if you would like to comment please leave a messge.
