Paste your SFX files (.wav .mp3 .aif .aiff .m4a .aac) into this folder.
Sub-folders work too (e.g. sfx/Whoosh/  sfx/Pop/ ...) - they appear in the panel under the folder name.
In the panel, open Step 40 'Sound Design (SFX)' and press Reload.
Pop.wav / Click.wav / Whoosh.wav are only test samples - you can delete them.
