China DOS Union

For example:
I want to know whether the C:\ABC folder exists. How should I judge it under DOS?

Does IF EXIST only judge files and not folders?

Just use IF EXIST C:\ABC\NUL.

I'll try!!!

It worked! Haha!

Thank you, moderator!!

Still need to trouble you!!!
/NUL
What does this parameter mean?

In fact, you can also use IF EXIST C:\abc\. or IF EXIST C:\abc\*.*
In addition, the software LOCATE is the most powerful for finding directories and files.

It's like this.

It doesn't work!!
The above is only effective when there are files in the directory
It has no effect on empty directories!!!!

/NUL can judge empty directories!!!

So please talk about./NUL.... Thank you!

In pure DOS, ABC\*.* may not be effective when there are no files, but it is effective under DOS32. NUL is used to determine whether the null device exists.

Oh!
