Basically your input file will be 4 way multi file..and lets say your file is partitioned on key {A}..then after input file add a partition by key and then add gather before output file (in case you dont need sorted data otherwise use partition by key and sort) and your output file location should point to 2 way mfs.

Converting the depth of a multifile is called repartitioning.
Read the source file -> Merge -> Reformat -> Partition by round-robin ->send it to new MFS with required partition.
It applies to any-way to any-way partitioning.
