Checking for File after particular period of time

I want to check for an excel file in different server after particular period of time (say 20 minutes). So, how can I complete this task. Any help will be appreciated

You can use Delay Activity to wait for a period of time.

But Bro, I want to iterate the activity in every 20 minutes. You told to use delay activity that will work once as I’ll start the process, but I want the process to check for the file without starting the process again and again.

Use a “File Exists” activity if that works and put it in a do while loop with a delay of 20 minutes.
The loop should break if the file is found.

P.S : I’m not sure if File Exists would work if the file is on a different server. But if it’s an accessible network drive then it should.
