@Richard019_RJ for each file (thats not a folder) has an extension infront of them which starts with (.) and end with the type like .rar .zip .iwi .iwi
you can turn it on to see what type they are watch this video to enable it

and again make sure that the files with .iwi are in images folder where i said you should put them
and .iwd files being one folder outside of images folder which is going to be in t6 folder
Also remember that the files you download theyre names will have numbers behind them and theyre ~ symbol change to - or _
you must go back to where you downloaded them and rename them in how they look it the post OR THEY WOULD NOT WORK!
