After following this post https://forum.step-project.com/showthread.php?tid=228&pid=7820#pid7820 to optimize HRDLC1 & HRDLC2, is the preferred method still to install them as loose files? If using them as loose files, is there any reason to keep the original files (HighResTexturePack01.bsa, HighResTexturePack01.esp, HighResTexturePack02.bsa, HighResTexturePack02.esp) in the data directory or can they be removed?
