* Moves the file from the src to dst. Does not keep the original file. If
the dst has parent directories
- * that haven't been created, this method will create all the necessary
parent directories. If dst already exists,
- * it will overwrite. Will work either for moving a directory or a file.
Currently assumes that both the srcUri
- * and the dstUri are of the same type (both files or both directories). If
srcUri is a file, it will move the file to
- * dstUri's location. If srcUri is a directory, it will move the directory
to dstUri. Does not support moving a file under a
- * directory.

- * For example, if a/b/c is moved to x/y/z, in the case of overwrite, a/b/c
will be renamed to x/y/z.

+ * If src is a file and dst is a directory, src file will get copied under
dst directory.
+ * If both src and dst are directories, src folder will get copied under dst
directory.

Review comment:
Clarify behavior if src is dir, dst is file, and overwrite is true. Looks
like LocalFS succeeds.
