Batch script to print the file names

For writing a script file

There are multiple ways we can print the file names

use the dir command and result of the filenames piped to filename.

@echo off

dir /b /a-d > filenames.txt
dir /b "c:/work" /a-d > worknames.txt

On running the info.bat file,

@echo off: commands execution does not print the commands
first dir command, creates filenames.txt created , contains file names in a current directory where script executes
second dir command,worknames.txt created with filenames list in the directory specified(c:/work)
using for loop

for loop in batch used to iterate each file in a directory and print the file name

@echo off

set "folder=."

for %%I in ("%folder%\*") do (
    echo %%~nxI
)

Following are steps

Current directory is set to . in a variable folder
Iterate each file name in a folder give,
%%I is a varialbe to points to file object
%%~nxI used to print the file name, n is the file name, x contains extension.
use %%~nI to get only file name without extension.
you can change folder variable point to any other folder that can be path to an directory.
