You moved the files, did you change the url in the database?

You should still be able to run it. Try this in your text editor (NOT VISUAL EDITOR). Of course change the url and video name, etc..

You can FTP the file into your WP-CONTENT/UPLOADS folder, then use “Add From Server” plugin to add it to your media on WP, then use “Flowplayer HTML5 for WordPress” plugin to play it.

localhost is a topic in and of itself. Read the documentation and follow it step by step. I personally haven’t done it.

IS your site a self hosted wordpress.org site or wordpress.com? If it’s a self hosted site you should have FTP access. Contact your host in how to establish an FTP connection. As both myself and @tara have explained, this is how you need to fix your issue.

WordPress is database driven. What this means is that all your settings, pages, posts etc is stored in the database unlike with an html site where you have everything in 1 file or more files. Local host is where you set up a WP site on your computer (offline). I suggest just playing around with your WP site to see how it works. Pretty much everything works from your dashboard, If you want a new theme, go to themes, click on ADD THEME and you will have literally thousands of themes to choose from. Plugins add functionality to your site. There is a difference between Pages and Posts although they use the same editor. Pages are single pages where as Posts are more like a forum with categories etc. You can find lots of youtube videos covering just about everything in the use and building of a WP site.

WordPress is pretty easy, but reading the documentation will help. https://codex.wordpress.org/Main_Page
