You need to have show hidden files set in your file explorer or you won't see files starting with a full stop, in this case .Kodi

I use ES file explorer from the play store

Thanks I just tried Es explorer I have ticked show hidden files but the org.xbmc.kodi file still shows as ? And I cannot do anything with it!?!?!?!?!?!!

Keep calm, keep calm :-) it's only a background

I do not understand what you mean "the org.xbmc.kodi file still shows as ?".

When you see the folder named org.xbmc.kodi you select it in the same way as you must have selected the data folder (?) and it should drill down a folder level and you shoud see the 'Files' folder select that and keep going until you are in the 'backgrounds' folder, then replace the default_bg.jpg with a picture of the same name that you wish to display, job done
