Alternative for FileUtil in Build

Hi everyone, I've just learned that "using UnityEditor" wasn't used in builds. My problem is that i've used FileUtil.DeleteFileOrDirectory to delete a file at a given path. And i need to use UnityEditor to use FileUtil. I know that it's impossible to use UnityEditor for builds, so i ask if there is any alternative for FileUtil.DeleteFileOrDirectory without UnityEditor (for builds). Thank you very much, have a nice day.
