You know, there is another approach you could take rather than moving 10 GB worth of files. If all those files are in a directory under your username “adjacent” to your web directory (such as having a directory structure that has /home/username/mediafiledirectory and /home/username/youdomainname.tld) you might find it "easier/faster to “copy” or “move” (or even download) the files in your /home/username/yourdomainname.tld directory to a “temporary” location, and then just “rename” your /home/username/mediafiledirectory to /home/username/yourdomainname.tld.
Once you do that, just re-upload, or copy/move the “html” files you stored temporarily into that “new” /home/username/youdomainname.tld directory (which now already contains all your media files) and you are all set, with everything you need in a web accessible directory.
There are several variations on that concept that would work, including just moving the contents of your “web” base directory into you media directory, and then renaming, or moving you r media directory into a "sub-directory of itself, and then moving the html into the “parent” of the new media directory (the “old” media directory) and then renaming it to be your base “web” directory - I think you get the idea here.
I’ll guarantee you it will be a lot quicker/simpler to use any of those methods (involving moving only the few files that comprise the contents of your “web” directory) than to move 10GB of files from your “media” directory to a new location.
