Hey @sarath_123
Are you providing the right file path in the source path for the file action? Can you try this:

Try adding the link to item from the shareppoint action. Alternatively, what you can do is, add a respond to powerapps action and send the link to item in the response. Now append '&download' to that link and upon button press you shpould be able to directly download the file without using the file system connector.
Hope this Helps!
