If you want to copy the entire source directory to the destination one, you can do so like this:
Directory to; // the directory to copy to for (String file : dir.listAll()) { dir.copy(to, file, newFile, IOContext.DEFAULT); // newFile can be either file, or a new name }
NOTE: this method does not check whether dest exist and will overwrite it if it does.

Directory.IndexInputSlicer
for the given file name.
IndexInputSlicer allows other Directory
implementations to
efficiently open one or more sliced IndexInput
instances from a
single file handle. The underlying file handle is kept open until the
Directory.IndexInputSlicer
is closed.
