Do not misquote me, and do not remove important parts if you are quoting.
I wrote ‘another’ within quotes. Since you are either not smart or just unwilling to understand it, let me explain.
The FILE is the same, the CONTENT of the file will be different. (Where ‘file’ means file path / file name / file extension)

No, we have not. I wrote, ‘abort if exist’. There is one call for output existance. The rest is exactly the same. OS does not know nor care about overwrite. It just dumps data to where you want it.
Learn how to code yourself if you don’t believe the ones who do know.

This is called a ’save as’, since there is not yet a file, nor known file name. The coder who wrote the app is smarter than you, he anticipated that you do not know that you cannot do a ’save’ on a non-existing / unknown file, so he made it an automagically ’save as’ instead of ’save to oblivion’.

And I am VERY sorry that I have to agree with Harald.
