You can use a `prune` option to specify the amount of disk space you would like username_0 Core to use. This option allows you to keep only the latest block information instead of storing all the data.

1. find your configuration file `username_0.conf` ([here](https://en.username_0.it/wiki/Running_Bitcoin) you can find the list of possible locations depending on your operating system);
2. set `prune` parameter to the desired target size in MiB (for example, `prune=2048`);
3. restart the wallet.
