Ive been wanting to use this addon rogue UI ( http://wow-en.curse-gaming.com/downloads/details/7110/ultimate-rogue-ui/ )

How ever it says to do alot in it, such as delete all my addon files and folders and all my WTF folders, which is quite drastic, so I was wondering, do these work for SURE? and if they dont is their anyway to get my ordinary addon's and WTF folders and files baq?

I am not a huge fan of compilations because you are taking somebody else's idea of what a Ui should look like and forcing it upon yourself.

If this is a Compilation you would like to try however, you can always make a backup copy of your interface/addons/ directory and WTF directory. Just make a copy of these two folders and put them somewhere else. If this compilation doesn't do what you want it to do you can delete the AddOns and WTF directory from the compilation and copy your old ones back into there.

You can simply right click your wow exe icon, goto properties/find target. The files in question will be there and al I do to try things is cut and paste them to the desktop. If the package is horrible, simply delete theones you tried and replace the others back. No mess, no fuss!!

If you are about to use a compilation, this is the best way to approach it.

First, copy your addons directory to a safe place and then delete it from the WoW directory. Then, go into the WTF folder and then the folder called account. you will see a folder with your account name. Click it once to highlight it and do a copy. Go to a safe place on your hard drive and paste in the folder. You know have a back up of your WTF folder. Once you know it's backed up safely, delete it and do what the compilation tells you. If you don't like the compilation, delete the directory and copy your old one back.
