We had some remarks:

• when the %temp% isn't defined it is possible that the wrong
  files will be deleted. First check: does mine %temp% variable exist.
  Secondly check: do the directory exist.
  
• with a del you are only deleting files in specified
  directory. Subdirectories and files in subdirectories will not
  be deleted.
  A better suggestion is: use deltree command, which can
  handle also open files. Other commands will stop processing
  your command.

  
  We suggest to modify it to:
  

  code:

  ---

  
    IF (len("%temp%") <> 0)
      IF (Exist("%temp%\nul") = 1)
        run '%comspec% /c echo Y|del %temp%'
      ENDIF
    ENDIF
  

  ---

  a better suggestion is:
  

  code:

  ---

  
    IF (len("%temp%") <> 0)
      IF (Exist("%temp%\nul") = 1)
        run '%comspec% /c deltree /y %temp%\.'
      ENDIF
    ENDIF
  

  ---

  a last suggestion is:
  

  code:

  ---

  
    IF (Exist("c:\winnt\temp\nul") = 1)
      run '%comspec% /c deltree /y c:\winnt\temp\.'
    ENDIF
    IF (Exist("c:\windows\temp\nul") = 1)
      run '%comspec% /c deltree /y c:\windows\temp\.'
    ENDIF
    IF (Exist("c:\temp\nul") = 1)
      run '%comspec% /c deltree /y c:\temp\.'
    ENDIF
  

  ---

  
  Only files and subdirectories in specified directories will be deleted.
  The names aren't influenced by other settings and you know that the
  specified directories can do any harm by deletion.
  Greetings.
