If you have any ENB files that aren't being picked up by this tool, select them from your game directory in your file explorer and click and drag them onto the detected files area of the manager.
Some ENB configurations come with there own custom lot of files that it pulls from.
WHY AREN'T ALL MY ENB FILES BEING DETECTED? You can then install any other configs you may have without having to worry about files conflicting. It will display what has been deleted if anything has at all. It will delete all instances of ENB, FXAA, ReShade and SweetFX from the selected directory. Make sure the path points to your Skyrim install directory, if not make it do so.
Run "ENB and ReShade Manager.exe" from anywhere on your PC.
