# ​Attachment Reuse

You can re-use attachments uploaded in a previous scenario step. To do this, get the attachment UUID from the source envelope and set it for the respective attachment in the target envelope.

You can’t use the same attachment UUID more than once in the same envelope. Attachment re-use works only for envelopes created via scenarios.

**Source envelope**

Example source envelope:

```markup
<envelope templateUuid="bd6c94c9-715f-4611-bcb0-cc4114cff83d" templateVersion="bd6c94c9-715f-4611-bcb0-cc4114cff83d">
        <info>
                <subject>envelope subject</subject>
                <message/>
                <forwarding delegation="true" sharing="true"/>
        </info>
        <flow>
                <roles>
                        <role id="e1bcbffa-aed6-4022-baef-40dee2da8cef" mailboxUuid="8dcde243-a918-444a-ac7d-44ac88554769"/>
                        <role id="bc749581-1685-4650-8e91-f2c7187d7223" mailboxUuid="8dcde243-a918-444a-ac7d-44ac88554769"/>
                </roles>
        </flow>
    <documents>
                <document id="aa620e04-852b-4ae4-85d4-833f5fdfc79f">
                        <field name="File 1" attachmentUuid="5c03bf5e-b2f3-44bb-b313-eb432830189d">zipFileName.zip</field>
                </document>
                <document id="fc246044-bfa5-4224-8329-7656280ac45c">
                        <field name="b70d61fa-4805-4e7b-9561-aa1f4f5c653f" attachmentUuid="e3760a4e-4c7b-4323-aa7b-60a4351ba8ef">pdfFileName.pdf</field>
                </document>
        </documents>
</envelope>
```

To re-use attachments from the source envelope, use one of these patterns:

```markup
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        ...
        <field name="File 1">
            <xsl:attribute name="attachmentUuid" select="envelope/documents/document/field[@name='b70d61fa-4805-4e7b-9561-aa1f4f5c653f']/@attachmentUuid"/>
        </field>
        ...
    </xsl:template>
</xsl:stylesheet>
```

Or:

```markup
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        ...
                    <xsl:variable name="att1Uuid" select="envelope/documents/document/field[@name='b70d61fa-4805-4e7b-9561-aa1f4f5c653f']/@attachmentUuid"/>
        <field name="File 1" attachmentUuid="{$att1Uuid}"></field>
        ...
    </xsl:template>
</xsl:stylesheet>
```

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://support.docstudio.com/user/scenarios/condition-types/attachment-reuse.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
