+Try to use org.apache.commons.io.FileUtils (General file manipulation utilities). Facilities are provided in the following methods:
+
+ (1) FileUtils.moveDirectory(File srcDir, File destDir) => Moves a directory.
+
+ (2) FileUtils.moveDirectoryToDirectory(File src, File destDir, boolean createDestDir) => Moves a directory to another directory.
+
+ (3) FileUtils.moveFile(File srcFile, File destFile) => Moves a file.
+
+ (4) FileUtils.moveFileToDirectory(File srcFile, File destDir, boolean createDestDir) => Moves a file to a directory.
+
+ (5) FileUtils.moveToDirectory(File src, File destDir, boolean createDestDir) => Moves a file or directory to the destination directory.
+
+It's simple, easy and fast.
