How many GB is Defrag?

2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Defrag is a game about cleansing corrupted sectors and refining them through optimization to build a stronger system. Collect resources, adjust configurations, and complete your build as you progress.
