Can I change the crunching noise without a FC?

Spoiler below!

<Resources>
<Directory Path="/_temp" AddSubDirs="true" />
<Directory Path="/fonts" AddSubDirs="false" />
<Directory Path="/maps" AddSubDirs="true" />

How would I change the resource folder?
Could I accomplish this by having a ui folder in my sounds folder of my FC?
