FileExists returns True if a file with name FileName exists on the disk, False otherwise. On windows, this function will return False if a directory is passed as FileName.
On Unixes, passing a directory name used to result in True. (The rationale is that on UNIX, a directory is a file as well). As of version 3.2.0, this behaviour has been changed for a Delphi-compatible approach.
Note that this function accepts a single filename as an argument, without wildcards. To check for the existence of multiple files, see the FindFirst function.
