Installed wordpress – public html folder

Hi everyone. I was hoping that someone can answer this question for me as I see different answers in different places.

I just did a wordpress install following the directions found on this site: https://wpcandy.com/teaches/how-to-install-wordpress

It worked, but my question now is: I seem to have more files in my FTP root folder than usual. I usually install wordpress using fantastico but for some reason it didn’t work, so I had to do it manually.

Here are some files I have. Can someone please let me know if anything needs to be removed? (These are in my public HTML folder)
