Before discussing downloading, one must understand what you’re getting. The Mega Database is not a raw PGN dump. It is a curated, indexed ChessBase (.cbh) format database that includes:

Over 100,000 deeply annotated games with comments from GMs like Karsten Müller, Mihail Marin, and Jan Gustafsson.

Direct engine links – Each game is pre-processed for Fritz / Fat Fritz / Stockfish integration.

Player & tournament encyclopedia – Bio data, peak rating, and head-to-head stats.

Key distinction: The Mega is strictly master-level (roughly 2000+ FIDE). The Big Database is larger but lower quality. The Correspondence Database is separate.
