当我这样做时
robocopy ./empty_folders ./empty_folders_dest /E
我看到以下选项：
Options : *.* /S /E /DCOPY:DA /COPY:DAT /R:1000000 /W:30
参数/S（不包括空目录）如何进入，/E逻辑排除（包括空目录）？倒数（逻辑上）不正确：当我/S时，我看不到/E。
进一步详情：
wmic datafile where name="C:\\Windows\\System32\\robocopy.exe" get Version /value
Version=10.0.16299.15
ver
Microsoft Windows [Version 10.0.16299.125]

你误解了文档。运行“robocopy / ???”看到完整的内置帮助。
/S :: copy Subdirectories, but not empty ones. /E :: copy subdirectories, including Empty ones.
换句话说，/ S将复制子目录除以外的子目录。 / E将复制子目录包括空目录。

使用/ MIR开关时，我的情况相同，但是如果没有它，这两个开关不会自动添加。因此，我建议这种情况可能与其他使用过的开关有关。
带有/ MIR开关的Robocopy：
#include <vector>
#include <cstdio>
using namespace std;
vector<size_t> transfo (const vector<size_t>& C)
{
vector<size_t> V (C.size());
for (size_t i=0; i<C.size(); i++)
{
V[i] = 0;
for (size_t j=0; j<C.size(); j++)
{
if ((j&i)==i) { V[i] += C[j]; }
}
}
return V;
}
int main()
{
vector<size_t> C = {
/* 000 */ 0,
/* 001 */ 5,
/* 010 */ 10,
/* 011 */ 2,
/* 100 */ 11,
/* 101 */ 3,
/* 110 */ 6,
/* 111 */ 4
};
vector<size_t> V = transfo (C);
for (size_t i=1; i<V.size(); i++) { printf ("[%2ld] C=%2ld V=%2ld\n", i, C[i], V[i]); }
}
不带/ MIR开关的自动复制：
