After the core import is done:
cd /var/www/html/wp-content/
cat uploads_chunk_* | tar -xzf -
Re-assemble chunks and extract. Then fix permissions:
chown -R www-data:www-data uploads
find uploads -type d -exec chmod 755 {} \;
find uploads -type f -exec chmod 644 {} \;
This method works 100% of the time for sites up to 200GB, provided you have SSH (command line) access or a robust file manager (cPanel). You do not need to use the web uploader at all.
