This configuration parameter specifies the minimum free disk space in kilobytes (KB) that is required for a group policy update. If the free disk space in any folder specified in is less than this value, then group policy settings will not be updated.

When updating the configuration file, the Perl mapper scripts create a temp file, print to it, and replace the original file. If the disk is full, the mapper cannot write to the temp file, so the temp file is empty, and the original file is replaced by the empty temp file. This configuration parameter and prevent the mapper writing to a temp file when disk space is low.

The default value is 5120 KBytes. Set this parameter to 0 to not check free disk space.
