Uploading files in cPanel
If you would like to upload some files to your server using cPanel, you can do so with built-in File Manager.
How to use File Manager:
Login to cPanel as user you've previously created:
https://<your_server_ip>:2083 or https://<your_server_ip>/cpanel
If you have not created user yet you can take these steps to do that now:
Now when you're in, press "File Manager"
Now you can select directory for uploading files. If the files are your web site, you should place them to "www" or "public_html" folder. And if you don't want your files to be web accessible you should upload them to some other folder. Using Filemanager you are also able to create new directories and delete existing.
