Send Scanned File to E-mail

I have a program that searches a file and the program says that my import (FileUtils) is not existing in the packages.. does this mean i need to download a seperate package for this?

here is the code

Code :

import org.apache.commons.io.FileUtils;
import java.io.File;
import java.util.Collection;
import java.util.Iterator;
 
public class SearchFile{
	public static void main(String[] args) {
		File root = new File("D:\Program Files");
 
	try {
		String[] extensions = {"txt"};
			boolean recursive = true;
 
	Collection files = FileUtils.listFiles(root, extensions, recursive);
 
	for (Iterator iterator = files.iterator(); iterator.hasNext();) {
		File pfile = (File) iterator.next();
		System.out.println("File Found: " + pfile.getAbsolutePath());
	     }
	} catch (Exception e) {
		e.printStackTrace();
	}
    }
}
