# Pentaho address to a VFS connection

The Pentaho address is the Pentaho virtual file system (`pvfs`) location within your VFS connection. When you are locating a file under the VFS connection category in the file access dialog box, the directory path in your Virtual File System appears in the address text box.

When you click in the address bar, the Pentaho address to the file appears in the text box.

You can copy and paste a Pentaho address into file path options of PDI steps and entries that support VFS connections.

**Note:** You must use the Pentaho virtual file system for anything related to Amazon S3. In addition, file paths and permissions in your existing transformations and jobs that use Amazon S3 are supported when **Amazon S3** is the **Default S3 Connection**.

## Querying This Documentation
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, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/data-integration-perspective-in-the-pdi-client/virtual-file-system-browser/pentaho-address-to-a-vfs-connection-open-a-transformation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
