In this Java tutorial we learn how to use the FileUtils class of Apache Commons IO library to copy multiple files to a given directory.

How to add Apache Commons IO library to your Java project

To use the Apache Commons IO library in the Gradle build project, add the following dependency into the build.gradle file.

implementation 'commons-io:commons-io:2.8.0'

To use the Apache Commons IO library in the Maven build project, add the following dependency into the pom.xml file.

<dependency>
  <groupId>commons-io</groupId>

  <version>2.8.0</version>
</dependency>

How to Copy List of Files to Directory using FileUtils class

The following example Java code shows you how to copy multiple files to a given directory using the FileUtils.copyToDirectory() method.

CopyListOfFilesToDirectory.java 

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class CopyListOfFilesToDirectory {
    public static void main(String... args) {
        try {
            List<File> listOfFiles = new ArrayList<>();
            listOfFiles.add(new File("D:\\Data\\data.txt"));
            listOfFiles.add(new File("D:\\Data\\data1.txt"));
            listOfFiles.add(new File("D:\\Data\\data2.txt"));

            File destinationDirectory = new File("D:\\TestData");

            FileUtils.copyToDirectory(listOfFiles, destinationDirectory);

            System.out.println("Copy List of Files to directory " + destinationDirectory + " success!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
The output is: 
Copy List of Files to directory D:\TestData success!

Happy Coding 😊
