If you are moving the files within the same filesystem, you can use the
Java File object to rename it like a Unix mv command.
See java.io.File.renameTo()

If you are going off the file system then you will have to do a copy and
delete. The copy would presumably be done using Buffered Streams. Be
careful not to ignore any exceptions since there could be an incomplete
copy and you'd then delete your source without a backup.
