...My latest script doesn't remove blank lines because TW asked me for it not to remove them
But now, the script works well for you, right?

yes, it works for me. so i'm getting a bit ambitious but with my limited skill in AHK, i need your help...
i want to add a check-box that overwrites the output file (see screenshot) which i've managed but i can't implement in the code.

Gui, Add, Checkbox, x16 y115 CheckedGray vOverwrite_File, Overwrite output file?
...
;Refer check-box option, to overwrite existing output file?
If Overwrite_File
 IfExist,%filetowrite%
   {
    FileDelete,%filetowrite%
   }

now the above code doesn't overwrite the existing file, it only appends it. do you know why?
