# Archive Rules

This article explains how archiving works in Model Reef.

You will learn:

* What it means to archive a model.
* Who can archive and restore models.
* How archiving affects access and collaboration.

Archiving is used to tidy up workspaces and preserve historical models without deleting them.

### What archiving does

When you archive a model:

* The model is moved out of the main active workspace view into an archive area.
* All branches, variables, Data Library entries, dashboards, reports and valuation settings are preserved.
* Notes, comments, tags and attachments are kept with the model.

{% hint style="info" %}
Archiving does **not** delete the model. It simply hides it from regular day to day lists.
{% endhint %}
{% endstep %}

{% step %}

### Who can archive and restore

Only **Owners** can:

* Archive a model.
* Restore an archived model back into the active workspace.
* Permanently delete a model if this capability is enabled in your account.

Editors and Viewers cannot archive or delete models.
{% endstep %}

{% step %}

### Effects on permissions and collaboration

When a model is archived:

* Existing permissions (Owner, Editor, Viewer and branch level access) are preserved.
* Collaborators no longer see the model in their normal workspace lists.
* If the model is restored later, all permissions and collaboration artefacts become active again.

Attachments remain stored with the archived model and are available again on restore.
{% endstep %}

{% step %}

### When to archive a model

Typical reasons to archive a model include:

* A project or transaction has completed.
* A financial year or planning cycle has ended and a new model has been created.
* A scenario or version is no longer actively used but must be kept for reference or audit.

Archiving helps keep the workspace focused on current work without losing historical models.
