FileExists
Check whether a particular file exists in the file system.
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.
