# Working From Older Files

## Working From Older Files

* If you have a file that was created with an older version, you might get a warning saying

`Warning: This strand is outdated, further editing is not possible. Please go to Hair Tube Builder -> Menu -> Update version`

* If you know your file was built with V14.03 or V14.05 or above, you can update it by going to **Menu-> Update V14.03/V14.05 to current.** Then re-select the strands and if you see the attributes show up in the Strand Editor, that means the file has been successfully updated.

{% hint style="danger" %}
If your library assets were saved before V15.04. After import, strands will not show up in the Strand Editor if you select them. Please update them by Menu > Update V14.03/14.05 to current. Once they are updated, you can then save them back to the library. Unfortunately, there's no way to automate this process.
{% endhint %}

{% hint style="danger" %}
Please Do NOT save an library item using older files.
