### The immich_model-cache volume takes up a lot of space, what could be the problem?

If you installed several models and chose not to use some of them, it might be worth deleting the old models that are in immich_model-cache. To do this you can mount the model cache and remove the undesired models.

### How can I purge data from Immich?
|

Data for Immich comes in two forms:

|
||||
1. **Metadata** stored in a Postgres database, persisted via the `pg_data` volume
|
||||
1. **Metadata** stored in a Postgres database, stored in the `DB_DATA_LOCATION` folder (previously `pg_data` Docker volume).
|
||||
2. **Files** (originals, thumbs, profile, etc.), stored in the `UPLOAD_LOCATION` folder, more [info](/docs/administration/backup-and-restore#asset-types-and-storage-locations).
|
||||
|
||||
To remove the **Metadata** you can stop Immich and delete the volume.
