The Azure Data Lake Store File System Task lets users perform various file system operations on Azure Data Lake Store (ADLS).

The Azure Data Lake Store File System Task is a component of the SQL Server Integration Services (SSIS) Feature Pack for Azure.

To add an Azure Data Lake Store File System Task to a package, drag it from SSIS Toolbox to the designer canvas. Then double-click the task, or right-click the task and select Edit, to open the Azure Data Lake Store File System Task Editor dialog box.

The Operation property specifies the file system operation to perform. Select one of the following operations:

  • CopyToADLS: Upload files to ADLS.
