John, John, John. *sigh* You didn't answer his question. You should
have said, "Yes", and then given the perldoc references.

However, be careful if later on performing any action based on the
knowledge that at some point in the history the file did exist.

Most often, one is interested, whether a piece of data can be read
from a file - and in this context it'd be better to attempt to
open the file and read the data. Just encapsulate the functionality
performing this to allow an upper level to process and report the
error appropriately.
