Extract complete source code of a website

Good evening, download FileZilla and enter your credentials in the designated fields. There, you will connect to your server where all your original website files will be deposited. A simple copy-paste from your server to your PC will be sufficient.

Here is a link that explains in more detail the use of FileZilla:

If you really don't have the correct credentials, you will only be able to retrieve the HTML code by right-clicking on your web page and selecting "view page source" (excluding the PHP code which is not visible).
