# Asset metadata and tags

Each asset in CKBox holds various metadata that serve numerous purposes while managing your files. Information such as the file upload date, file size, and dimensions is stored in the file metadata and accessible after selecting the file and invoking the **Properties** panel.

<a id="metadata">

## Metadata

To see or change the metadata of one of your files, select the file in the main window and click the **Properties** icon in the top bar. The file information panel will appear, letting you apply desired changes. Each asset has a unique URL that you can use to access it. You can easily copy it to the clipboard with a single click.

<a id="name">

### Name

The file name can be changed in the **File name** input field. Please observe that changing the file extension will not convert the file to a different format! You can also use the **Rename** button from the top bar.

<a id="description">

### Description

Adding a file description can improve the search. This description will also be automatically added in the [`alt` attribute of an image embedded in CKEditor 5](../../../../../ckeditor5/latest/features/images/images-text-alternative.md), enhancing the accessibility of the produced content.

### Custom attributes

Using the [REST API](../../rest-api.md), you can define custom attributes for each asset. This might be useful for your integration.

<a id="tags">

## Tags

You can add tags to any file to enhance search and descriptions. This kind of taxonomy lets users attach keywords describing the asset and assign them into groups. To tag one of your files, select it in the main window and click the **Properties** icon in the top bar. A dedicated panel will appear. Enter all desired tags in the **Tags** input field. You can paste the tags from the clipboard and copy them to the clipboard with the built-in copy button right from the input field. Once done, save the changes.
