[batch-file] Delete files in subfolder using batch script

I had to complete the same task and I used a "for" loop and a "del" command as follows:

@ECHO OFF

set dir=%cd%

FOR /d /r %dir% %%x in (archive\) do (
    if exist "%%x" del %%x\*.txt /f /q
)

You can set the dir variable with any start directory you want or used the current directory (%cd%) variable.

These are the options for "for" command:

  • /d For directories
  • /r For recursive

These are the options for "del" command:

  • /f Force deletes read-only files
  • /q Quiet mode; suppresses prompts for delete confirmations.
