# 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, refer to the Content component Reference.

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.
