Fastest way to copy files in Java

Question

What ist the fastest way to copy a big number of files in Java. So far I have used file streams and nio. Overall streams seem to be faster than nio. What experiences did you mak

Answer 1

You can use either FileUtils implementation of apache commons-io library to copy file

FileUtils.copyFile(new File(sourcePath), new File(destPath));

Which uses FileChannel for IO operation.

Or use java.nio.file.Files's copy() method.
