vba程序，按顺序打开目录下文件，运行已有的宏。(vba procedures, in order to open the directory file, and run existing macros.)

Conceptually, a merge sort works as follows Divide the unsorted list into n sublists, each containing 1 element (a list of 1 element is considered sorted). Repeatedly merge sublists to produce new sorted sublists until there is only 1 sublist remaining. This will be the sorted list.
