Nice nytmar3. Good to have different options.
The reason that I did my pack the way I did was so you have the file with the exact name it needs to be to show up in XBMC without having to rename it at all. Unfortunately, this requires you to have them in separate folders because there can't be two files with the same name in a folder (of course). Also, I did it that way to give credit to the artist if we knew who did it.
There will only be one more update with my pack though, as I won't continue collecting any more icons at this point.
Later,
