I've been using LMDE for a while now but haven't changed mt setup much recently.
I decided to change a theme the other day and was refused permission to extract the file to the directory. I remembered having to open files with root authority (or whatever) before so back tracked but can't find any setting to do this. Am I being thick here, or have things changed and I'm just not aware of them. I have a bad cold at the moment, so that's a good excuse for my brain not working but it strikes me that this has got to be something simple, but I just can't see it.
Any suggestions please!
