If you’re working with a complicated site then you may find that importing files and posts into WordPress is a bit of a black art – there are lots of places where things might go wrong. If the
upload_url_path value for your site has been manually changed, then this might cause problems with WP export files.
Q: why would you change
upload_url_pathlets WordPress serve images etc. from a subdomain or different domain, which should improve site performance if you have an image-heavy site.
