Answer 1

If Remover is an MVC action than I cannot see the parameter in Remover Action called fileName

It means when call Remover action the fileName in your querystring is not getting automatic model binding

Answer 2

Your controller action should take "fileName" parameter, instead of doing a Request["fileName"]. As long as your query string parameter matches the name of the parameter in your controller mvc should pass it in automatically.
