go into the folder that contains the mlc parts, go in the address box, type cmd, in cmd prompt, type this (you may not have a part 16 as the mlc can either be 29.1 or 29.7GBs iirc, depending on the chip in your system. it won't matter as it will skip over it if you don't need it:
copy /b mlc.bin.part01 + mlc.bin.part02 + mlc.bin.part03 + mlc.bin.part04 + mlc.bin.part05 + mlc.bin.part06 + mlc.bin.part07 + mlc.bin.part08 + mlc.bin.part09 + mlc.bin.part10 + mlc.bin.part11 + mlc.bin.part12 + mlc.bin.part13 + mlc.bin.part14 + mlc.bin.part15 + mlc.bin.part16 mlc.bin
