# Recommended s3 object paths

## 2025-02-1

We strongly advise using **S3 object paths** rather than file names to extract metadata (e.g., year, exchange, instrument).

### ⚠️ Current vs Proposed File Names

* **Old**: Filenames contain metadata and are human-readable.
* **New**: Filenames use generated IDs; metadata is stored in the **S3 path**.

### ✅ Why It Matters

* More stable, structured access.
* Avoids breakage from file naming changes.
* Simplifies workflows.

### 🛠️ What You Should Do

If you currently parse filenames, update to extract metadata via the object path instead.
