Filezilla... is it just one step, drag and drop, or is it two steps?

Question

I have a one page website up and running that is labeled "index html"

I recently modified the whole website in my documents folder and that will end up with the same label "index html"

Now, when I am connected to my website using FileZilla, do I need to take two steps (Download the existing file, and then upload the new file) OR do I just go to the new file on the left and drag it into the old file? Will this second method do both things, upload the new file AND download the old file in one step?

So which is it? One step or two steps?

Answer 1

Drag and dropping will overwrite the old file.  So if you want to save a copy of your old site, download it first, then drag the new one over.
