China DOS Union

Automatically delete all autorun.inf files with any attributes from any directory on all drives:
@ECHO off
FOR %%c in (Z,Y,X,V,U,T,S,R,Q,P,O,N,M,L,K,J,I,H,G,F,E,D,C) do (
IF exist %%c: (
del /f /s /a /q %%c:autorun.inf
)
)


The second line checks whether drive %%c exists. My question is: can DOS recognize that (Z,Y,X,V,U,T,S,R,Q,P,O,N,M,L,K,J,I,H,G,F,E,D,C) represent drive letters?
A newbie's confusion

Delete @ECHO off
Run this batch file in the command interpreter and you'll know

Haha, HAT again. I tried it in CMD and it showed: %%c was unexpected at this time
Does HAT mean that if it errors after running, there will be an error message, right?

So this post originally came from here

Change %%c to %c, then run it in the interpreter

In a FOR loop, isn't the control variable written with %%?
Do you mean changing the IF line?

In a batch file the control variable is %%c
If you run it directly in the command interpreter, the control variable is %c

Thanks, HAT. HAT is really too good. If I have questions later I'll have to trouble you more, and ask for more guidance

Just because I have free time and practiced hands, that's all.
I really can't be called “too good”; the experts will laugh at me.
Let's all learn from each other.

I just looked at the usage of FOR again, and now I understand that %% is used in batch files. Haha, I learned a little more. Many thanks to HAT, thanks
