# User profile

User profile is a collection of settings and application data associated with a specific user. In a non-persistent remote environment, such as Parallels RAS, user profiles must be maintained to provide consistent user experience. This is achieved by storing user profile data in a network location to minimize sign in times and optimize file I/O between host, client, and the profile storage.

Parallels RAS supports the following technologies to manage user profiles:

* [**User profile disk**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/rd-session-hosts/manage-rd-session-hosts/manage-hosts-rd-session-hosts/user-profile/user-profile-disks.md): \[RD Session Hosts only] These are virtual hard disks that store user application data on a dedicated file share. This disk is mounted to the user session as soon as the user signs in to a session host. The disk is unmounted when the user logs out.

{% hint style="info" %}
**Note**: The User Profile Disks technology is no longer being actively developed by Microsoft. It's recommended to migrate profiles to [**FSLogix**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/rd-session-hosts/manage-rd-session-hosts/manage-hosts-rd-session-hosts/user-profile/fslogix.md)**.** Please note that the **User profile disk** option is not available for VDI and Azure Virtual Desktop due to obsolescence.
{% endhint %}

* [**FSLogix**](/landing/ras-admin-guide/parallels-ras-21-administrators-guide/rd-session-hosts/manage-rd-session-hosts/manage-hosts-rd-session-hosts/user-profile/fslogix.md): A remote profile solution for non-persistent environments. FSLogix Profile Container redirects the entire user profile to a remote location and maintains user context in non-persistent environments, minimizing sign-in times and providing native profile experience eliminating compatibility issues. FSLogix Profile Container is the preferred profile management solution as the successor of Roaming Profiles and User Profile Disks.

User profiles can be configured for the following:

* RD Session Hosts
* VDI
* Azure Virtual Desktop

User profile settings are configured for the above on the Site level (Site defaults) and can also be configured for individual components if the RAS administrator decides to use custom settings for a given component.

To configure user profile on the Site level, navigate to **Farm** > **Site**, click the **Tasks** > **Site defaults** menu and choose one of the following:

* **RD Session Host**
* **VDI**
* **AVD multi-session hosts**
* **AVD single-session hosts**

In a Site defaults dialog that opens, select the **User profile** tab. The user interface for configuring optimization is the same for all of the above.

The subsequent sections describe in detail how to configure the user profile functionality.

## 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-admin-guide/parallels-ras-21-administrators-guide/rd-session-hosts/manage-rd-session-hosts/manage-hosts-rd-session-hosts/user-profile.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.
