In checking this box, the utility uses another API. Instead of applying the function ''To record'' of SOLIDWORKS, the utility makes a ''To record under'' by replacing the existing file.

Indeed, in certain cases under Windows, when one always saves a file under same name, it appears that its abnormally grown size (it is true for all the software under Windows). The trick thus consists in making a ''To record under'' another name, the size can thus be decreased (but it is not systematic!). To check this option amounts automating this procedure.
