China DOS Union

I remember someone said before that it seems that by taking the first 3 characters of the variable %cd%, there is a single command for that.

%CD% does not necessarily represent the directory where the batch file is located, but rather the current directory when you run this batch file. Suppose like this:

D:\DOS> c:\batch\my.bat

Then %CD% represents the d:\dos directory, while the directory where my.bat is located is c:\batch.

If in cmd, you can use %~dp0 to represent the drive letter where the batch file is located.

Thanks for the previous answer, but I misunderstood it.

Can this effect be achieved?

When this bat file is run, it will echo the drive letter where this bat file is located.

Someone said before that it can be done with one command

@echo off
echo Current path is: %cd%
echo Current drive letter is: %cd:~0,1%
pause

Thanks for the solution from the user above XD~

Thanks to the upstairs for the answer XD~

Actually, the person on the 2nd floor is correct, he didn't misinterpret.

And the person on the 4th floor is not completely correct, although in most cases the result is the same.

So, I need to remind you that the people you should thank the most are the person on the 2nd floor and me.

Seeing a problem shouldn't rely on imagination; only practice can yield true knowledge.

```
@echo off
echo %~d0
pause
```
