Hi jaygrg, yes it should be feasible. You would need to pass all 20 into the arcgisonlineconnector with upload action. The file parameter would be an attribute value of the filepath. So before the connector, place a reader or feature reader with format = directory file path

then in the connector use the @value(path_windows) for File

Hi @jamesb16otterill​  yes it worked perfectly. Thank you so much!
