How do I import a file name under a folder into a text document?

The first step is to open the folder and create a new text document, as shown in the following illustration:

Open the new text document and enter the following code:

@echo off

dir/b/on >list.txt

Then change the file name format to. bat format

You will be prompted to change the file name extension, may cause the file is not available, are you sure you want to modify it? Click Yes

Double-click the. bat file, and in the same folder will generate List.txt, file, open to see if you need something inside?
