如果父位置中存在folder1，则尝试创建folder2 ..似乎无法使其工作。尝试使用powershell，但由于某些原因它不会从服务器运行，因此我试图完成批处理。
for /f "delims=|" %%s in ('dir /ad/b')
(
if exists "%%s\Folder1" do md "%%s\Folder2"
)
答案 0 :(得分：1)
for /f "delims=|" %%s in ('dir /ad/b') DO (
if exist "%%s\Folder1" md "%%s\Folder2"
)
注意：缺少DO;开括号必须与DO在同一物理线上; EXIST，而不是EXISTS。 DO错误地将IF错误地包含在@ECHO Off

已经存在。
结果（插入一点空格）
do所以 - 对我有用 - 在if语句中的do is not recognised ...被移除后，但会产生%%s错误，而不是{{1}}，因为您已经报告
