Java: Move Directory containing files and directories to new path

Question

I have one directory containing some files and sub directory having more files in it.

Folder -  Directory (path -> /home/abc/xyz/Folder)
  ->Abc.txt  (file)
  -> Xyz.zip (file)
  -> Address (Sub Directory)
         -> PWZ.log (file)
         -> CyZ.xml (file)
  -> DataLog.7zip

etc

What I am trying to do is move this complete Directory from one path to another including all the files and subfolder(and their files).

ie Move this "Folder" from /home/abc/xyz/Folder to /home/abc/subdir/Folder.

Does Java provides any API to do this task based on FOLDER directory or do we need to do recursive copy each and every file only to this path?

Answer 1

You can simply move directory by using

import static java.nio.file.StandardCopyOption.*;

Files.move(new File("C:\\projects\\test").toPath(), new File("C:\\projects\\dirTest").toPath(), StandardCopyOption.REPLACE_EXISTING);

Change source and destination path

Refer here to get more details

Also Note from API

 When invoked to move a
     * directory that is not empty then the directory is moved if it does not
     * require moving the entries in the directory.  For example, renaming a
     * directory on the same {@link FileStore} will usually not require moving
     * the entries in the directory. When moving a directory requires that its
     * entries be moved then this method fails (by throwing an {@code
     * IOException}). To move a <i>file tree</i> may involve copying rather
     * than moving directories and this can be done using the {@link
     * #copy copy} method in conjunction with the {@link
     * #walkFileTree Files.walkFileTree} utility method

If you try to move the file in the same partition , the above code is sufficient ( it can move directory even it has entries). if not ( instead of move) you need to use recursive as other answer mentioned.

Answer 2

   private static void move(File sourceFile, File destFile) {
        if (sourceFile.isDirectory()) {
            File[] files = sourceFile.listFiles();
            assert files != null;
            for (File file : files) move(file, new File(destFile, file.getName()));
            if (!sourceFile.delete()) throw new RuntimeException();
        } else {
            if (!destFile.getParentFile().exists())
                if (!destFile.getParentFile().mkdirs()) throw new RuntimeException();
            if (!sourceFile.renameTo(destFile)) throw new RuntimeException();
        }
    }

works for me
