Description

Tests whether a specified file exists.

FileExists returns True if the file specified by FileName exists. If the file does not exist, FileExists returns False.

Note: If the FileName parameter is a symbolic link and the FollowLink parameter is set to True, the method is performed on the target file. If the first condition is True, but the FollowLink parameter is set to False, the symbolic link is used, regardless whether the link is broken (the target file is invalid).

Method behavior if the FileName parameter is a file:

File Exists	FollowLink	Method result
YES	True	True
YES	False	True
NO	True	False
NO	False	False

Method behavior if the FileName parameter is a symbolic link:

Target Exists	FollowLink	Method result
YES	True	True
YES	False	True
NO	True	False
NO	False	True
