Declaration

Source position: filutilh.inc line 182

  function FileExists(const FileName: UnicodeString; FollowLink: Boolean)
                      : Boolean;
  function FileExists(const FileName: RawByteString; FollowLink: Boolean)
                      : 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.
