# Partitioning

To increase the flexibility of KeyView output, you can output the HTML rendering of different parts of a file to different partitions. These partitions are snippets of HTML output for a given portion of the file. The calling code can then combine these partitions into the desired output structure. This option allows for highly flexible and customizable output.

You can enable partitioning by using fpSetPartitionOn. You can obtain information about each partition by using fpGetPartitionInfoList.

The KeyView interface allows you to create new partitions for several reasons. The following table lists the available reasons.
