C # file splitter

When combined, two layers of copy commands can be combined, and some files can be combined. In fact, the general length of the test command line can theoretically realize the combination of unlimited split files, but the practical value is not high, and the demolition of 10,000 documents. Not only is this single-threaded method, not only the efficiency is low, but it should be divided and combined with a better algorithm. This program can eventually be classified as "toys".
