Introduction

Copying options are listed here:

  • REPLACE_EXISTING: If the copied file already exists, then it is replaced. For a symbolic link, the target is not copied, only the link is copied.
  • COPY_ATTRIBUTES: Copy a file with its associated attributes (at least, the lastModifiedTime attribute is supported and copied).
  • NOFOLLOW_LINKS: Symbolic links should not be followed.

To copy only the symbolic link itself, use the REPLACE_EXISTING and NOFOLLOW_LINKS options.
