In the created zip file > backup > wp-content
there are several "uploads" folders:
which are not in my site's contents folder. They contain anywhere from nothing, like the uploadsadministrator, that ends up at a blank html file; to a abstract collections of php files (uploadswp-admin & uploadswp-includes); to what looks like just a collection of redundant files (uploadswp-content) already elsewhere in the backup.
Why are they there, and how do they play into the restore process?
