The site configured at this address does not contain the requested file

I’m new to GitHub, recently I created my first ever repository and uploaded files from my computer into the repository I created, I just basically dragged and dropped the entire project folder and followed along all the steps in the tutorial. Now that I’m trying to visit the webpage, I’m receiving the following message ’ 404, file not found, the site configured at this address does not contain the requested file. If this is your site, make sure that the filename case matches the URL.
For root URLs (like http://example.com/ ) you must provide an index.html file.’

Can anyone tell me what the issue is?

From the screenshot it looks like you put your files into a subdirectory. Whatever you want to show up when someone visits your github.io domain must be at the top level of your repository.

By subdirectory you mean Project I folder?

Yes, exactly. What’s in there should be visible if someone adds “Project I” to the path, though.

Okay I’ll try doing it that way. Thanks
