In this article, you’ll learn how to copy a non-empty directory recursively with all its sub-directories and files to another location in Java.
Java copy directory recursively
import java.io.IOException;
import java.nio.file.*;
public class CopyDirectoryRecursively {
public static void main(String[] args) throws IOException {
Path sourceDir = Paths.get( "/Users/project/Desktop/new-media");
Path destinationDir = Paths.get("/Users/project/Desktop/media");
// Traverse the file tree and copy each file/directory.
Files.walk(sourceDir)
.forEach(sourcePath -> {
try {
Path targetPath = destinationDir.resolve(sourceDir.relativize(sourcePath));
System.out.printf("Copying %s to %s%n", sourcePath, targetPath);
Files.copy(sourcePath, targetPath, StandardCopyOption.REPLACE_EXISTING);
} catch (IOException ex) {
System.out.format("I/O error: %s%n", ex);
}
});
}
}
