Which type of files are typically stored on Resolve's scratch disk?

• A. Source media files
• B. Timeline project notes
• C. Ancillary/cache files Resolve creates
• D. Rendered exports

Answer: (C)

Scratch disk holds temporary, non-essential data that helps Resolve run faster. This is where it writes ancillary cache files the software creates during editing—things like render cache, optimized media, thumbnails, and other cache-related data. These files are meant to speed up playback and processing, not to store your original media or final outputs. The source media stays on its own drives, timeline notes live in the project database, and rendered exports are the completed videos you save to a chosen location. So the best answer is the one describing Resolve’s cache/auxiliary files. You can control the scratch disk location in the preferences, which is useful for managing disk space.
