I'm trying to modify files in the /root folder but I can't because I don't have permission.

I don't understand what is happening because i thought i'm logged in with the root but the name is just different.

I can't even add a new file, for example I'm trying to add a text file to the "www" folder to try and add a php file to run in Apache but i can't add a file.

However when i access the terminal and work with sudo it works fine but i want to do it the normal way.

The question here: how to grant my user full root privileges ? (Because i want to add and edit the "www" folder)

I'm supposed to be the root but my user directory is not in the root it is in the home directory :( What's wrong ?!!!
