This very small .bat file is for converting BC7 (optimized for Skyrim SE as well as FO4, but not compatible with Skyrim LE) format .dds file to uncompressed 8.8.8.8 ARGB, which is compatible for Skyrim LE, by Texconv .   Thus, you can relatively easily back-port some Skyrim SSE exclusive textures in BC7 format to LE without relying on Intel Photoshop plug-in (as well as Photoshop). How to use: Download Texconv.exe from its Github and this .bat file, and put both files in the same directory.
