# Remove sensor, node or folder

To remove a tree view element like sensor, node or folder, right click it and select “Remove” from the context menu.

The system is protecting its infrastructure so in case you try to remove an element that has influence on some other system parts, like a PC node, a warning will be displayed informing that the deletion cannot be performed.

To remove any node you have to first remove all other elements like other nodes or sensors that use this specific node for their operation.

In case it is possible to remove the element, a dialog is opened to confirm removal of the element.

Click “Yes” to remove or “No” to cancel the operation.

Sign the operation.

If you want to remove a folder, please be aware that this operation removes all the elements inside the folder and also all the elements outside the folder that use nodes inside the folder for their operation. Please be careful using this method and always double check the elements you remove.

The system does not keep information about the nodes removed but it does remember information about all removed sensors. If you want to look at any measurements or events of a removed sensor, select “Show Removed sensors” option from “View” in the main menu. The removed sensors will be listed in a “Removed sensors” folder in the tree view.

## 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://help.boomerang3.com/boomerang-2-system-administrator-manual/tree_view/remove_sensor-_node_or_folder.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.
