# Compact the Data Index

(Applies to IDOL Content and IDOL Agentstore components, DIH, and IDOL Proxy)

After documents are deleted, the data index contains unused spaces. Compacting the index reduces its size by moving documents into the unused spaces. The `DRECOMPACT` action performs this task. For more information about the `DRECOMPACT` action, see the IDOL Server Reference.

To compact the data index

1. In the Service Control tab in the Console page, click Compact.

   A confirmation message appears.

2. Click Compact.
