1. How do I check in the working directory whether a specific directory exists, and create that specific directory if it doesn't exist

2. Does anyone know how to use the "FOR" command in a batch file?

1.
if not exist .\特定目录\nul md .\特定目录

2.
C:\>for /?
Executes a specified command for each file in a set of files.

FOR %variable IN (set) DO command

%variable specifies a replaceable parameter.
(set) specifies a set of one or more files. Wildcards may be used.
command specifies the command to execute for each file.
command-parameters
specifies parameters or switches for the specified command.

If you use the FOR command in a batch program, specify %%variable instead of
%variable. Variable names are case-sensitive, so %i is different from %I.

Thanks
