# Compress the Data Index

You can configure the Content component to compress the `nodetable` directory to reduce the disk footprint, by using the NodeTableCompression configuration parameter.

NOTE: If you change the compression method after you have started the server, the compression applies only for operations that index new data or rewrite existing data (such as DREREPLACE).

To compress or change the compression of the whole index, you can run a DRECOMPACT operation with the `NodeTableCompactWindowKB` NodeTableCompactWindowKB parameter set.

For more information about the NodeTableCompression option, and the compression method to use, refer to Knowledge Discovery Expert.

To configure the Content component to compress the nodetable index

1. Open the Content component configuration file in a text editor.

2. In the `[Server]` section, add the NodeTableCompression parameter and set it to the compression method that you want to use to compress the index.

   You can set it to one of the following values:

   - `zlib`

   - `snappy`

   - `lz4`

   - `lz4hc`

3. Save and close the configuration file.

4. Restart the Content component for your changes to take effect.
