In XP make a folder for walls in the : /Windows folder, try naming it : /00_Walls or something that will keep it at the top of the folder.
Most screenies can be found in : /Windows/system 32 under XP.
You can stash walls just about anywhere you like as long as you remember the location ..... screenies are best loaded into the default folder, unless you have the option of specifying where you want them.
