Batch file and DEL errorlevel 0 issue

Question

The batch has to remove files and directories from specific locations and output success or stdout/stderr messages to a new .txt file. I have created the most of the script

Answer 1

The answer of aschipfl is great (thanks, helped me a lot!) using the code under Presetting ErrorLevel you get a nice standard function:

Take care to use %~1 instead of %1 in the del statement, or you will get errors if you use a quoted filename.

::######################################################################
::call :DELETE "file.txt"
::call :DELETE "file.txt" "error message"
:DELETE
  >nul ver && for /F "tokens=*" %%# in ('del /F /Q "%~1" 2^>^&1 1^> nul') do (2>nul set =) || (
    if NOT .%2==. echo %~2
  )
goto :EOF

BTW 1: You can give a nifty error message as a second parameter
BTW 2: Using :: instead of REM for comments makes the code even more readable.
