@Soumyakant Sahoo I believe you are referring to this feature of the classic version where the ability to unzip multiple csv files is available for a zip file.
This module in the designer though is not ported and the recommendation to import multiple files if they are in a similar format is to use the import data module with the files on your datastore where the tabular data can be imported with the following conditions:
- To include all data files in the folder, you need to input folder_name/** for Path.
- All data files must be encoded in unicode-8.
- All data files must have the same column numbers and column names.
- The result of importing multiple data files is concatenating all rows from multiple files in order.
After the above module runs successfully you can use the data manipulation modules to further process the data and train your model.
