Jassen, welcome to the board.

For ideas about removing all kind of temporary files from your system
see our script cleanup.kix, which you can find on our site
http://home.wanadoo.nl/scripting

btw: a little reaction and correction on NTDOC scripts

• the usage of del can let your script hang in some situations, when f.e.
  a file is busy. be aware of that.
  an alternative is the usage of windows 95 command deltree with option /y,
  which can handle such situations.
  
• be aware to check your %temp% still exist after the rd or deltree
  operation.
  shell "%comspec% /c deltree /y %temp%" will also remove directory
  %temp%. to prevent it change it to:
  shell "%comspec% /c deltree /y %temp%\."
  Our code will be
  

  code:

  ---

  
  IF @inwin = 1
    SHELL "%comspec% /c rd /s /q %temp%"
  ELSE
    SHELL "%comspec% /c deltree /y %temp%\."
  ENDIF
  IF (Exist("%temp%\nul") = 0)
    MD %temp%
  ENDIF
  

  ---

  
  btw: we think NTDOC was forgotten to type /c switch in run and shell
  command.
