Hi @rudraPraveenKumar ,
Please use the File transfer activity and select the external account and put the filter as shown below for .zip files
Also, please use the Data loading activity to read the file from the transition.
In the similar way , Please use the other file transfer activity same as shown above, but please change the filter from "*.zip" to "*.csv" to read the .csv files in that Directory.
Regards,
Pravallika.
