Description:  

This policy setting limits the number of ranges that can be added to a file in a BITS job. By default, files in a
BITS job are limited to 500 ranges per file. You can use this setting to raise or lower the maximum number
ranges per file.

       If you enable this setting, BITS will limit the maximum number of ranges that can be added to a file to
the specified number.

       If you disable or do not configure this setting, BITS will limit ranges to 500 ranges per file.

       Note: BITS Jobs created by services and the local administrator account do not count towards this limit.

Supported on: At least Windows Vista.
