+
+This part of data is crawled from web pages from the latest URLs obtained from FineWeb [8], a cleaned and deduplicated English dataset derived from Common Crawl.

+Since this portion of the data contains at least 1.6 million images, we have compressed them into 10 zip files, from `fineweb_3m_s11.zip` to `fineweb_3m_s52.zip`.
+
+Please extract them into the same directory.
