| All my files are .png files which will open in any graphics program with a transparent background. But to save on storage space the tubes are then zipped. The programI use is WinRAR, which is what you will need to unzip them. You can find WinRAR as a free download if you do a search for it. I do not use Winzip as WinRAR has superior qualities and actions. |
