Hi ALL...
I have a certain .jpg file in my "Home" folder named Smoke.jpg that I want to copy or move to my wallpaper file. I open my Home folder then right click on the .jpg file icon to bring up the menu that I assume will let me copy or move the file. I click on "browse" and follow the folder tree until I get to /opt/kde3/share/wallpapers
When I highlight that path and click I get the error message:
"Access denied
could not write to /opt/kde3/share/wallpapers/Smoke.jpg "
Why?

ls -ld /opt/kde3/share/wallpapers and check the permissions.

It's the directory protections.
Use the root console and type

# mv Smoke.jpg /opt/kde3/share/wallpapers

Maybe I should be over in the abject Newbie forum...
I don't know how to "check permissions" and I don't know how to get to the root console.
The only time I have ever had to login as "root" is when I am trying to use the Yast configuator thingie.
I have a thing called "Konsole-terminal program" which looks like some kind of thing that you use to enter raw linux commands, but I have no idea how to use it.
I'm afraid that, if you folks are willing, you'll have to hold my hand and walk me through this simple task...step by step from power up.

i don't know KDE but i would be pretty sure kde has a local user wallpaper folder (/home/you/desktop/wallpaper maybe??), and not just a system wide one (the /opt/ one). but as far as what you've already been advised, yes that Konsole thingy is a "console" or "Terminal emulator" in that box you need to enter the commands above.

basically as you are not root, you are not allowed to copy a file to a system wide location (i.e. anywhere outside of /home/you save for a few exceptions, e.g. /tmp) so you need to become root to do this. i think kde also has a "root konsole" option, but you can just open any console and run "su" then enter the root password. once you're root, that mv (move) command should work just fine.

You don't need to copy the wallpaper to the system folder. Just keep it somewhere in your homedirectory and point to this place from the KDE control center.

But if you still want to copy it, do it like acid_kewpie suggested. There is a root-version of the konqueror somewhere in the 'system' menu which you could use if you'd like to do it the clicking way.
