Error when building mod with Sm4sh Explorer

[ShiroTheHero]

After loading the files into the program, when I try to build the mod so the file appears in the export folder, an error comes up stating " that an Unhandled exception has occured and that the access to the path is denied. No idea what's causing this.

Check your export folder and delete the file manually. It was probably locked when the program tried to delete it.
