I have looked around but it seems the website is providing no way to view/modify/delete the files. It only had GIT, and I guess, seeing some of the search results, I could use a special command-line app to do that. Isn’t there any way to use just the web browsers to do those things?
I mean, something like drag-and-drop modified directory again to overwrite previously uploaded directory? I tried that, but it created a new website (now I have two). I guess I could delete the previous one and rename the new one to the previous name, but that sounds cumbersome. Nothing like an FTP or web-based file manager like the good old webhosting sites?
