How Do I Properly Remove Sample Content Before Marketplace Audio Submission

[Likedrebel]

Hello,
I have read about the Config folder, Content folder and .uproject file when submitting. I have an audio submission, SFX. How do I make sure sample content is not loaded or how do I delete it as requested? I can’t find steps how to do this.
Thank you.

After the developing/testing stage I usually migrate stuff i need 100% to a new empty project
