You're downloading a newer version of an Asset Pack; how will you avoid duplicating assets?

• A. Unity's Import Window should show you which are already imported and not allow you to reimport, unless there are changes
• B. Duplicates are overwritten automatically
• C. You must manually delete any duplicates
• D. Unity prompts you to rename duplicates

Answer: (A)

When updating an Asset Pack, the import process is designed to prevent duplicates by showing you what’s already in the project and only reimporting what has actually changed. Unity tracks assets in the Asset Database with unique identifiers, so when you bring in a newer version, the Import Window can identify which files are already present and skip reimporting them if their content hasn’t changed. If a file in the new pack is different, Unity will reimport and update that asset rather than creating a duplicate. This makes updating clean and avoids clutter from duplicate assets.

That’s why this option is the best: it relies on the import workflow to compare existing assets and only bring in updates, rather than blindly duplicating everything. Duplicates aren’t overwritten automatically, you don’t typically have to manually delete duplicates, and there isn’t a general prompt to rename duplicates during a standard asset update.
