    FileExists

    Check whether a particular file exists in the file system.

    Declaration

    Source position: filutilh.inc line 224

    function FileExists(const FileName: UnicodeString; 
                   FollowLink: Boolean=True) : Boolean;

    function FileExists(const FileName: RawByteString; 
                   FollowLink: Boolean=True) : Boolean;

    Description

    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.

    Errors

    None.
