1048   * copied to their locations.
1049   *
1050   * The files in the `$_old_files` list will be removed and the new files

1055   *
1056   * The steps for the upgrader for after the new release is downloaded and
1057   * unzipped is:
1058   *
1059   *   1. Test unzipped location for select files to ensure that unzipped worked.
1060   *   2. Create the .maintenance file in current WordPress base.
1061   *   3. Copy new WordPress directory over old WordPress files.
1062   *   4. Upgrade WordPress to new version.
1063   *      1. Copy all files/folders other than wp-content
1064   *      2. Copy any language files to `WP_LANG_DIR` (which may differ from `WP_CONTENT_DIR`

1072   * 6, then you will not be able to access any portion of your site. Also, since

1074   * automatically remove old files and remove the 'update_core' option. This
1075   * isn't that bad.
1076   *
1077   * If the copy of the new WordPress over the old fails, then the worse is that
1078   * the new WordPress directory will remain.
1079   *
1080   * If it is assumed that every file will be copied over, including plugins and
1081   * themes, then if you edit the default theme, you should rename it, so that
