I have never found a reason to download a file from a web site to modify it. I've been creating web sites for 15 years or so. I ALWAYS keep a copy on a local server, test changes on that server and only upload via FTP when I know it's working.
If I have to work on a site previously written by someone else I download the complete site via FTP, make changes then upload it again.
