Usually I just right-click on a folder and I get the option of "root actions - open in new window" or something like that. I've got a local web server and I'm unable to transfer files into /var/www/html unless I'm root.

I can do it via terminal, but that's not as easy as "drag and drop" if I could have root access in a file manager.

I'm using Debian 8 with KDE as desktop environment.

I was looking for something like "options->root" or something.

Any help would be greatly appreciated.

Usually KDE offers a root file manager at Menu. Try go over if there is.

Another way is---

Alt+F2 then at the box type
Click Launch or OK. You will be prompted for your password.

Another way is---

Get a terminal or after you are set user as root, type . Instead of "dolphin" you can use "konqueror" any way the terminal should be able to offer you a root file manager. In my case I am using all those, save that I don't use dolphin very often, I mostly use Thunar the Xfce4 file manager.

Goodluck. Enjoy.

If you are using KDE, the command below will work to open the dolphin filemanager. Of course, you will prompted for your root password.

You can change ownership of sub-directories of the /html directory.

These commands did not work for me. Unable to locate package.

I had problems developing in the local server, for example the backgrounds would not load however developing using desktop and no PHP, the background problem was fixed.

Still I would like to figure out how to get root access for folders with GUI/drag and drop as opposed to using terminal to move files.

Try

I found that "kdesu" did not work in my Linux Mint 17 KDE. However, "kdesudo" did work.
"gksudo" definitely did not work well.

May not work in some cases but Arch you are using has at least one of the following command:
or you will be prompted with a password. Some commands like "gksudo", "gksu" are just links to "gnsu" they work the same way.

You have been told above by many and any of those opinions may run in your system. Actually "gksu", "gksudo" are gnome ways; while "kdsu", "kdesu", "kdsudo" are kde ways. Another way of knowing what your system is currently using is to try and you will know which of the above is available. However, the shortest way is in the terminal, then followed by issuing that should bring you to a root file manager.

There is no such thing as drag-and-drop implementation of set-user-to-root, so far to my limited information. But somehow you or any one can make a script to make that happen. Drag and drop is the gambit of proprietary OS's, making dangerous things easy for the customers in order to ensure business and profit. That seems to be far from philosophy of unix oriented OS's.

Hope that helps. Goodluck.

Don't be root, be the owner of the files you are working with.
