# Compact a series file offline

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

Use the **Series File Compaction tool** to compact your series file and reduce its size on disk. This is useful for series files that grow quickly, for example, when series are frequently created and deleted.

**To compact a series file:**

1. Stop the `influxd` process.
    
2. Run the following command, including your **data directory** and **WAL directory**:
    
    ```sh
    # Syntax
    influx_inspect buildtsi -compact-series-file -datadir <data_dir> -waldir <wal_dir>
    
    # Example
    influx_inspect buildtsi -compact-series-file -datadir /data -waldir /wal
    ```
    
3. Restart the `influxd` process.
    
4. ***(InfluxDB Enterprise only)*** On each data node:
    
    1. Complete steps 1-3.
    2. Wait for the [hinted handoff queue (HHQ)](/enterprise_influxdb/v1/concepts/clustering/#hinted-handoff) to write all missed data to the node.
    3. Continue to the next data node.
