Almost every software publisher is impacted by piracy, whether they know it or not. Some of the main files that are usually taken are:

Music

Movies

Editing software(Adobe, Microsoft, Autodesk, etc.)

Games

Piracy costs companies large sums of money, depending on how often their software is stolen. Each file stolen is a file the company doesn't make profit from, which could cost thousands, or even millions. Source: LegalBeagle Image source
