China DOS Union

I’m using a tool, and in DOS with a batch file
I want to generate a new file for every file in that folder, and at the same time have the new file use the same filename as the source file, but with a different extension. How do I do that? :o

Use the for command together with the ~n expansion parameter, then add your custom extension.

Say it a bit more specifically, the poster above

First use for to iterate through the contents of the folder, then generate the file as you want, and then use the %~na form to expand the filename; add the extension and that’s it. Isn’t that specific enough?

Check for/? and you’ll understand

If it’s pure DOS, the ~n expansion parameter won’t work

Does the OP want to do this under CMD or in pure DOS?
