@MattWho  Thank you so much for responding,    I want to rename the outgoing file as such "name_timestamp". want to name each file with the following standard "name"+"_"+"timestamp"   and the issue is solved after changing destination value from flowfile-content to flowfile-attribute initially it was pointing to flowfile-content and I dont see the custom extracted attributes in attribute section, but after changing to flowfile-attribute, I can see the extracted values in the attribute section   thank you very much ...
