Question

我有一个名为m_all的源文件夹，目标文件夹名为m_1, m_2, m_3... m_8。

我想将源文件夹中的文件复制到目标文件夹中，

以这样的方式将2个文件改为m_1，将3个文件改为m_2，将2个文件改为m_3，将3个文件改为m_4 ..

这些目标文件中没有模式。

我该怎么做？

Answer 1

这是一个基本的例子，（我确信那里有一种更聪明的方式）。它应该使用您提供的模式复制文件，直到没有复制文件为止。 （这意味着，例如，最后一个文件可能是唯一复制到m_3的文件）

                            If !i! LEq 17 (Copy "%%A" "m_7") Else (
                                If !i! LEq 20 (Copy "%%A" "m_8"
                                    If !i! Equ 20 Set i=0)))))))))

没有包含代码来满足复制现有文件的要求，即覆盖。

更改第3行上括号之间的位置以适合您的实际源目录路径。

Answer 2

这将在文件夹之间均匀分配文件，如果还有剩余文件，它们将被复制到最后一个文件夹

将在TK中收到输入文件夹。文件夹数量放在%1变量中。文件夹名称（%totalfolder% ... m_1）将分为两部分：m_8变量中的前缀（m_）和{{1}中计算的文件夹编号1}}变量

%folderprefix%

该脚本基本上维护每个文件夹中的文件数，如果文件夹完全填满，它将移动到下一个文件夹
