// This option provides a way to create a Junction instead of a
      // Directory symlink on Windows. This comes with the following caveats:
      // * NTFS Junctions cannot be relative.
      // * NTFS Junctions MUST be directories.
      // * NTFS Junctions must be on the same file system.
      // * Most products CANNOT detect a directory is a Junction:
      //    This has the side effect of possibly having a whole directory
      //    deleted when a product is deleting the Junction directory.
      //    For example, JetBrains product lines will delete the entire contents
      //    of the TARGET directory because the product does not realize it's
      //    a symlink as the JVM and Node return false for isSymlink.

// This function is Windows only, so we don't need to check again
