Why is an extra file being created in FOR loop of batch program?

Question

I\'ve written the following batch file to create multiple files using FOR loop:

@echo off  
cls  
FOR /L %%i IN (1 1 10) DO (  
    echo.> file%%i.txt

I don't know why, but when you write ... IN (*.txt) ... in the second for loop, it is trying to find files that are just created within the body of the loop.

To eliminate that, I would make my filter a bit more specific.

FOR %%i IN (file??.txt) DO (

I ran this and it creates only 20 files as expected.
