Hi Tom Abraham

Thanks for your question.

You're correct - Mapping Data Flows in Azure Data Factory do not support the AzureFileStorage linked service type, which is typically used for mounting Azure Files via SMB protocol.

Workaround:

To use your data in a Data Flow, you'll need to:

Copy data from Azure File Storage into a supported staging location, such as:

• Azure Data Lake Storage Gen2
• Azure Blob Storage

You can achieve this by:

1. Creating a Copy Activity in your pipeline that reads from Azure File Storage and writes to Blob Storage or ADLS Gen2.
2. Point your Mapping Data Flow source to the new location (Blob/ADLS Gen2).

This staging approach allows you to transform the data using Data Flows afterward.

Hope this helps. Do let us know if you any further queries.
