# Device and Resource Redirection
Generally, device redirection increases how much network bandwidth RD Session Host server connections use because data is exchanged between devices on the client computers and processes that are running in the server session. The extent of the increase is a function of the frequency of operations that are performed by the applications that are running on the server against the redirected devices. Printer redirection and Plug and Play device redirection also increases CPU usage at sign-in.
Parallels recommends to not allow device redirection if not being used since this will result in inefficient bandwidth usage. Local device redirection can be configured from Parallels RAS policies, registry, or Microsoft group policies.

## 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.parallels.com/landing/ras-best-practices-guide/remote-access-configuration/configure-remotefx/general-purpose-remotefx-settings/device-and-resource-redirection.md?ask=&goal=
```
`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.
