They are hidden from the file explorer and quick open, while indexing continues as before.
They are dropped from search results only, leaving the index and the AI context untouched.
They are excluded both from Cursor's index and from the context that reaches the AI.Correct answer
They are indexed as usual but marked with a warning whenever the Agent reads one of them.

Show answer & explanation

Correct answer: C. They are excluded both from Cursor's index and from the context that reaches the AI.

Explanation

The principle — An ignore file in Cursor is a context tool, not a display setting. It governs what enters the project index and what can be included in the material sent to the model.

Why the key is correct — Cursor describes ignore files as controlling which files it indexes and includes in AI context, so a generated folder listed there stays out of both. That is why excluding build output speeds indexing and keeps noise away from the Agent.

Why the others are wrong — Hiding files from the explorer or quick open is an editor convenience and a different feature. Trimming only search results would leave the index intact, which reverses the actual behaviour. Ignored files are also excluded rather than indexed and flagged on access.

Remember this — Ignoring is about context, not cosmetics.
