# Updating Collection Contents

## Overview

Collections in Publisher dynamically update based on filter settings. You can modify these filters anytime to change what content appears in your collection.

## Accessing Collection Filters

Open the collection editor using either method:

* **From the Collections page**: Click "Actions > Edit Collection" next to your target collection
* **From within a collection**: Click the "Edit Collection" button in the top-right corner

## Modifying Collection Filters

1. Select the "Files" or "Tables" tab in the filter panel
2. Customize your filters:
   * Name conditions (is, contains, starts with)
   * Data source type
   * Data source name
   * File attributes (suffix, size, type)
   * Additional metadata fields
3. Click "Apply" to preview your changes
4. Review the filtered results to ensure they match your needs
5. Click "Done" to save your updated collection

{% hint style="warning" %}
Changes to filters take effect immediately
{% endhint %}

## Managing File and Table Metadata

Each file or table in your collection can have its own metadata:

1. Navigate to the "Contents" tab in your collection
2. Select any file or table from the list
3. In the information panel, you can update:
   * File/table name
   * Description (supports rich text formatting)
   * Additional metadata fields
4. Click the save icon to preserve your change

## Key Points

* New content that matches your filters automatically joins the collection
* Existing content that no longer matches filters is automatically removed
* You can preview filter results before finalizing changes
* File and table metadata updates are independent of filter settings
