# Collections

Duplify exports all collections from your source store, including sorting arrangements, collection conditions, SEO information, and associated products. This ensures your curated product sets are preserved and can be replicated in your destination stores.

## Exporting collections with Duplify

When you select the **Collections** option in Duplify:

* All collections from your source store are exported to your destination stores.
* Each export includes the collection’s title, description, image, conditions, products, product sorting, and SEO information.
* You can also choose to include metafields and metaobjects associated with collections using the checkboxes.

### Export options

* **Existing collections**: When matching products exist in the destination store, choose to create new products, update existing ones, or ignore them.
* **Metafields:** Toggle the export of metafields on or off.&#x20;
  * **Note:** You also need to export **Shop metafields** to configure this export.
* **Collections filters**: Use filters to select specific products or groups of products to export. Filters can include date ranges, product types, tags, or other criteria.
* **Auto-sync**: Turn on Auto-sync to automatically carry over modifications, deletions, or new products from your source store to your destination stores. By default, Auto-sync is off. [Learn more about Auto-sync](/using-duplify/auto-syncing.md).

## Auto-sync

Auto-sync allows changes to source store collections, like modifications, deletions, or new collections, to automatically update in your destination store.&#x20;

You have a certain Auto-sync export limit in your plan tier, the same way you have a limit in other categories like Collections and Products.

* When exporting, use the toggle switch to turn Auto-sync on or off.
* By default, Auto-sync is **off**.

Learn more about [Auto-syncing](/using-duplify/auto-syncing.md).

#### Example

If your store has a “Summer Collection” with products sorted by price and specific collection conditions, exporting collections with Duplify replicates all details in your destination stores. If Auto-sync is enabled, then any updates to the collection automatically also sync to the destination store.

***

## Export events

Duplify tracks export events to determine the size of your store’s export. Each event represents one data item or file.

#### Collection export events

* Each collection exported counts as one export event.
* Products within the collection are required for export. Use the product filter tool to select the relevant products. Each product in a collection also counts as one export event.
* When Auto-sync is active, any new, changed, or deleted collection counts as one export event in the Auto-sync category.
