+## Download an example file
+
+Files can be uploaded and then referenced by agents or messages. Once it's uploaded it can be added to the tool utility for referencing. You can find a downloadable example file on [GitHub](https://github.com/Azure/azure-sdk-for-js/blob/main/sdk/ai/ai-agents/data/syntheticCompanyQuarterlyResults.csv).
