I wish to rename all files inside the folder *.txt, so the result will be "1.txt", "2.txt" and "3.txt", ....

How can I do so?

::Setup the stage...
SETLOCAL ENABLEDELAYEDEXPANSION
SET folder=C:\This\Is\The\Folder
SET count=1

::Action
CD "%folder%"
FOR %%F IN ("*.txt") DO (
 MOVE "%%F" "!count!.txt"
 SET /a count=!count!+1
)
ENDLOCAL

Shorthand

SETLOCAL ENABLEDELAYEDEXPANSION
SET count=1
FOR %%F IN (C:\Path\To\File\*.txt) DO MOVE "%%~fF" "%%~dpF!count!.txt" & SET /a count=!count!+1
ENDLOCAL

So if your folder contained cat.txt, dog.txt, bird.txt, ninjaturtle.txt, it will output 1.txt, 2.txt, 3.txt, 4.txt.
