hello monks

I am taking a file as an input from user , all I want is that if the user for the first time gives wrong file name which does not belong in a directory a message should be displayed , and should ask him to renter the name . How can I do it ?

One more question , how to check whether the file input by the user is present in directory or not ??

Thanks in advance
