Windows 10: This command not working: ren "A *.*" "*.*"

This command is not working for me: ren "A *.*" "*.*" I don't get an error, but file names do not change. Is this command incorrect?

:)

 

REN command is not working

I have written a simple batch file to rename all of the files with a same file extension inside a folder with consecutive number starting with one provided by the user. It works correctly when I use it with files named like "[We-now] Do It - 783 [spa]".****,
but when I try to use it in another folder with .mkv files, with file names like this "Now or Never - 130- Bryan's Return! Into Hell for Nairobi's fault! [1080p][x264][AAC][Eng-Sub]-df68.mkv" the command says it is not able to find the file. Same happens if
I just try to run the REN command from a cmd

Here is my code:

setlocal enabledelayedexpansion

REM //Setting working directory as current folder

SET "wp=."

REM // Asking user for extension to rename

SET /P ext="Extension of files to rename: "

REM // Asking user for the first number

SET /P fn="Introduce first number: "

SET /A i=%fn%

SET /A k=1

REM // We start renaming

FOR %%J IN ("%wp%\*.%ext%") DO CALL :rnaming "%%J"

goto End

:Rnaming

SET aux=%~nf1

ECHO %aux%

ECHO Iteration %k% - Next name: %i%

ECHO Renaming %~1

ren "%aux%" "%i%.%ext%"

SET /A i=%i%+1

SET /A k=%k%+1

:End

Thanks in advance for any help!

 

GPU-Z what command line parameter ?

Suggestion: /? (-?) and /help (-help) command-line arguments to show a list of all possible arguments in a small window. *Smile

 

Programs not working

In post 26 there were steps listed to fix the operating system corruption.
Are you able to follow them?
In post 29 was the suggested dism repair command.
