File trigger without keeping the orchestrator busy

Hello Folks,

Just wondering on the File trigger Activity, how can this be implemented having the following criteria:

  • monitors the file drop
  • when file is dropped, execute another job/process
  • Should not keep the orchestrator busy

does this criteria require any separate license or single unattended license will do the work, because when i am trying to run the background process it is making the orchestrator busy and putting every other job in pending state.

any ideas
