Note: Successfully executing this level of cleaning will require an understanding of plugin file format and close familiarity with powerful tools, sometimes including the CS.
Make sure to put the plugin name in double quotes if it contains spaces, and include the file extension. The current standard is to run ' tes3cmd clean 'plugin1.esp' '. Mod users should clean every plugin (.esp/.esm) file before using in-game. The levels are meant to be performed sequentially (Basic before Advanced before Mod Makers). It is divided into three sections for different levels of cleaning.
