The copyFileToDirectory() method of the FileUtils class of the ApacheSW Commons IOS library allows us to copy a file to a directory. It takes the source file as its first parameter and the destination directory as its second argument. If the destination directory doesn't exist, it will be created. The CopyFileToDirectoryTest class demonstrates this.

package test;



public class CopyFileToDirectoryTest {

	public static void main(String[] args) throws IOException {

		File file = new File("test1.txt");
		File destinationDir = new File("test-directory");

		FileUtils.copyFileToDirectory(file, destinationDir);



Before executing CopyFileToDirectoryTest, I had the test1.txt source file located at the root level of my project.

'testing' project

After executing CopyFileToDirectoryTest, you can see that the test-directory directory was created, with a copy of test1.txt in that directory.
