# Premiere OS Path Mapper Action

The Premiere OS Path Mapper Action ensures that all paths within a project are mapped correctly, depending on the operating system installed on the workstation that opens the premiere project. This node is necessary if several operating systems are used in the editing environment and you want to avoid manually linking the files in the project.

Before any manipulation of the project file is executed, a backup of the project file will be created with the extension '\*.prproj\_backup'. If the manipulation encounters an issue, such as creating a 0 KB project file, the backup file will be used to replace the corrupted file.

The prproj\_backup file is created by the following nodes:

* [Premiere Version Converter Action](/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/actions/adobe-premiere-pro/premiere-version-converter-action.md)
* [Premiere Path Settings Action](/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/actions/adobe-premiere-pro/premiere-path-settings-action.md)
* [Premiere OS Path Mapper Action](/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/actions/adobe-premiere-pro/premiere-os-path-mapper-action.md)
* [Premiere Generate UUID Action](/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/actions/adobe-premiere-pro/premiere-generate-uuid-action.md)
* [Project Version of Premiere Condition](/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/conditions/project-8/project-version-of-premiere-condition.md)

## 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.helmut.de/helmut4-releases/v4.10.0/helmut4-components/streamdesigner/nodes/actions/adobe-premiere-pro/premiere-os-path-mapper-action.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.
