This topic discusses the Folder Redirection, Offline Files (client-side caching or CSC), and Roaming User Profiles (sometimes known as RUP) technologies, including what's new and where to find more information.

Technology description

Folder Redirection and Offline Files are used together to redirect the path of local folders, such as the Documents folder, to a network location, while caching the contents locally for increased speed and availability. Roaming User Profiles is used to redirect a user profile to a network location. These features used to be referred to as Intellimirror.

  • Folder Redirectionenables users and administrators to redirect the path of a known folder to a new location, manually or by using Group Policy. The new location can be a folder on the local computer or a directory on a file share. Users interact with files in the redirected folder as if it still existed on the local drive. For example, you can redirect the Documents folder, which is usually stored on a local drive, to a network location. The files in the folder are then available to the user from any computer on the network.

  • Offline Filesmakes network files available to a user, even if the network connection to the server is unavailable or slow. When working online, file access performance is at the speed of the network and server. When working offline, files are retrieved from the Offline Files folder at local access speeds. A computer switches to Offline mode in the following situations:

    • Always Offline mode has been enabled.
    • The server is unavailable.
    • The network connection is slower than a configurable threshold.
    • The user manually switches to Offline mode by using the Work offline button in Windows Explorer.
  • Roaming User Profilesredirects user profiles to a file share so that users receive the same operating system and application settings on multiple computers. When a user signs in to a computer by using an account that's set up with a file share as the profile path, the user's profile loads to the local computer and merges with the local profile, if present. When the user signs out of the computer, the local copy of their profile, including any changes, merges with the server copy of the profile. Typically, a network administrator enables Roaming User Profiles on domain accounts.

Practical applications

Administrators can use Folder Redirection, Offline Files, and Roaming User Profiles to centralize storage for user data and settings. These features let users access their data while offline or in the event of a network or server outage. These features can also accomplish these specific applications:

  • Centralize data from client computers for administrative tasks, such as using a server-based backup tool to back up user folders and settings.
  • Enable users to continue accessing network files, even if there is a network or server outage.
  • Optimize bandwidth usage and enhance the experience of users in branch offices who access files and folders that are hosted by corporate servers located offsite.
  • Enable mobile users to access network files while working offline or over slow networks.

New and changed functionality

The following table describes some of the major changes in Folder Redirection, Offline Files, and Roaming User Profiles that are available in this release.

Feature/functionalityNew or updated?Description
Always Offline modeNewProvides faster access to files and lower bandwidth usage by always working offline, even when connected through a high-speed network connection.
Cost-aware synchronizationNewHelps users avoid high data usage costs from synchronization while using metered connections that have usage limits, or while roaming on another provider's network.
Primary Computer supportNewEnables you to limit the use of Folder Redirection, Roaming User Profiles, or both to only a user's primary computers.

Always Offline mode

Starting with Windows 8 and Windows Server 2012, administrators can configure the experience for users of Offline Files to always work offline, even when they are connected through a high-speed network connection. Windows updates files in the Offline Files cache by synchronizing hourly in the background, by default.

What value does Always Offline mode add?

The Always Offline mode provides the following benefits:

  • Users experience faster access to files in redirected folders, such as the Documents folder.
  • Network bandwidth is reduced, decreasing costs on expensive WAN connections or metered connections such as a 4G mobile network.

How has Always Offline mode changed things?

Prior to Windows 8, Windows Server 2012, users would transition between the Online and Offline modes, depending on network availability and conditions, even when the Slow-Link mode (also known as the Slow Connection mode) was enabled and set to a 1millisecond latency threshold.

With Always Offline mode, computers never transition to Online mode when the Configure slow-link mode Group Policy setting is configured and the Latency threshold parameter is set to 1millisecond. Changes are synced in the background every 120 minutes, by default, but synchronization is configurable by using the Configure Background Sync Group Policy setting.

For more information, see Enable Always Offline mode for faster access to files.

Cost-aware synchronization

With cost-aware synchronization, Windows disables background synchronization when the user is using a metered network connection, such as a 4G mobile network, and the subscriber is near or over their bandwidth limit, or roaming on another provider's network.

Note

Metered network connections usually have round-trip network latencies that are slower than the default 35 millisecond latency value for transitioning to Offline (Slow Connection) mode in Windows 8, Windows Server 2019, Windows Server 2016, and Windows Server 2012. Therefore, these connections usually transition to Offline (Slow Connection) mode automatically.

What value does cost-aware synchronization add?

Cost-aware synchronization helps users avoid unexpectedly high data usage costs while using metered connections that have usage limits, or while roaming on another provider's network.

How has cost-aware synchronization changed things?

Prior to Windows 8 and Windows Server 2012, users who wanted to minimize fees while using Offline Files on metered network connections had to track their data usage by using tools from the mobile network provider. The users could then manually switch to Offline mode when they were roaming, near their bandwidth limit, or over their limit.

With cost-aware sync, Windows automatically tracks roaming and bandwidth usage limits while on metered connections. When the user is roaming, near their bandwidth limit, or over their limit, Windows switches to Offline mode and prevents all synchronization. Users can still manually initiate synchronization, and administrators can override cost-aware synchronization for specific users, such as executives.

For more information, see Enable Background File Synchronization on metered networks.

Primary computers for Folder Redirection and Roaming User Profiles

You can now designate a set of computers, known as primary computers, for each domain user, which enables you to control which computers use Folder Redirection, Roaming User Profiles, or both. Designating primary computers is a simple and powerful method to associate user data and settings with particular computers or devices, simplify administrator oversight, improve data security, and help protect user profiles from corruption.

What value do primary computers add?

There are four major benefits to designating primary computers for users:

  • The administrator can specify which computers users can use to access their redirected data and settings. For example, the administrator can choose to roam user data and settings between a user's desktop and laptop, and to not roam the information when that user logs on to any other computer, such as a conference room computer.
  • Designating primary computers reduces the security and privacy risk of leaving residual personal or corporate data on computers where the user has logged on. For example, a general manager who logs on to an employee's computer for temporary access does not leave behind any personal or corporate data.
  • Primary computers enable the administrator to mitigate the risk of an improperly configured or otherwise corrupt profile, which could result from roaming between differently configured systems, such as between x86-based and x64-based computers.
  • The amount of time required for a user's first sign-in on a non-primary computer, such as a server, is faster because the user's roaming user profile and/or redirected folders are not downloaded. Sign-out times are also reduced, because changes to the user profile do not need to be uploaded to the file share.

How have primary computers changed things?

To limit downloading private user data to primary computers, the Folder Redirection and Roaming User Profiles technologies perform the following logic checks when a user signs in to a computer:

  1. The Windows operating system checks the new Group Policy settings (Download roaming profiles on primary computers only and Redirect folders on primary computers only) to determine if the msDS-Primary-Computer attribute in Active Directory Domain Services (ADDS) should influence the decision to roam the user's profile or apply Folder Redirection.

  2. If the policy setting enables primary computer support, Windows verifies that the AD DS schema supports the msDS-Primary-Computer attribute. If it does, Windows determines if the computer that the user is logging on to is designated as a primary computer for the user as follows:

    1. If the computer is one of the user's primary computers, Windows applies the Roaming User Profiles and Folder Redirection settings.
    2. If the computer isn't one of the user's primary computers, Windows loads the user's cached local profile, if present, or it creates a new local profile. Windows also removes any existing redirected folders according to the removal action that was specified by the previously applied Group Policy setting, which is retained in the local Folder Redirection configuration.

Hardware requirements

Folder Redirection, Offline Files, and Roaming User Profiles require an x64-based or x86-based computer, and they are not supported by Windows on ARM (WOA)-based computers.

Software requirements

To designate primary computers, your environment must meet the following requirements:

  • The Active Directory Domain Services (ADDS) schema must be updated to include Windows Server 2012 schema and conditions. Installing a Windows Server 2012 or later domain controller automatically updates the schema. For more information about upgrading the AD DS schema, see Upgrade domain controllers to a newer version of Windows Server.
  • Client computers must run Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, or Windows Server 2016 and be joined to the Active Directory domain that you're managing.
  • Deploy Folder Redirection with offline files

FAQs

What is folder redirection or roaming profiles? ›

Roaming User Profiles is used to redirect a user profile to a network location, whereas Folder Redirection enables users and administrators to redirect the path of a known folder to a new location, manually or by using Group Policy. So, the latter may allow for more granularity.

What is the difference between offline files and roaming profiles? ›

Folder Redirection and Offline Files are used together to redirect the path of local folders, such as the Documents folder, to a network location, while caching the contents locally for increased speed and availability. Roaming User Profiles is used to redirect a user profile to a network location.

What is folder redirection vs user profile disks? ›

Folder redirection allows users to be logged in to multiple servers at once without issue accessing files whereas with UPDs, a user cannot be logged into more than one RDS concurrently as their UPD will be locked for use on one server and inaccessible from another until properly dismounted after logging off.

Does offline files need to be enabled for folder redirection? ›

By default, the Offline Files feature is enabled for redirected folders on Windows client computers, and disabled on Windows Server computers. Users can enable this feature, or you can use Group Policy to control it.

Are roaming profiles a good idea? ›

While it's an attractive idea to have your files synchronized across different workstations, a roaming profile will take a long time to load if you have many files. There's also a possibility of file corruption during this process, so you need to have different kinds of backups for your files.

What is the purpose of roaming profiles? ›

A roaming user profile is a file synchronization concept in the Windows NT family of operating systems that allows users with a computer joined to a Windows domain to log on to any computer on the same domain and access their documents and have a consistent desktop experience, such as applications remembering toolbar ...

How do you tell if roaming profiles are being used? ›

Check if a device uses roaming profiles (optional)

To see if a Windows computer is using Roaming User Profiles, enter chrome://sync-internals in the browser window on that computer. On the About page, under Local state, find Local Sync Backend Enabled. If it's true, then Roaming User Profiles is enabled.

What happens if I delete roaming folder? ›

Can I Delete the Local, LocalLow, and Roaming Folders? Yes, but no. Deleting these folders can not only possibly break Windows, but they will also indeed remove most of your program settings. Since these folders are protected, you'd have to boot into safe mode, then delete them and immediately regret it.

Is the roaming folder important? ›

Roaming is ideal for corporate environments, including settings such as Outlook profiles and networked printer configurations. It helps bring consistency to a user's environment across different machines within a network by storing user-specific settings and files.

What is the benefit of folder redirection? ›

Some of the advantages of folder redirection are: user documents are available from any computer. helps to reduce logon and logoff times (data is stored outside the user profile)

What is the best practice for folder redirection? ›

For optimal performance of the Folder Redirection feature, it is strongly recommended that you create only the root share on the server, and then let the system create the folders for each user.

What are the benefits of user profile disks? ›

Ensuring users have a consistent experience, regardless of the endpoint from which they access their remote resources, is an important aspect of managing an RDS deployment. User Profile Disks (UPDs) allow user data, customizations, and application settings to follow a user within a single collection.

What is the difference between Folder Redirection and roaming profiles? ›

Roaming profiles store registry settings, whereas folder redirection stores files. A home folder is not the same as folder redirection. Although both reflect the designation of a centralized storage location for user data, there are some key differences.

Where are roaming profiles stored? ›

A roaming profile is stored on a central server which can be accessed from all domain computers. This allows you to have the same environment settings on every machine to which you log on. Your roaming profile is copied to a machine when you log on, and the synchronized back to the server when you log off.

How do I know if Folder Redirection is working? ›

How to verify that folder redirection works
  1. In a session, navigate to a folder you directed, right-click the folder, and then select Properties.
  2. In the properties window, navigate to the Shortcut tab and then check the Target field. If the field displays a redirected path, folder redirection works.

What is a folder redirection? ›

Folder Redirection is defined by automatically re-routing standard folders to use storage on another server. There are specific folders on a WSU employee's workstation that are storing the files or data on a separate server. The separate server can also be described as file shares.

Is it OK to delete Roaming folder? ›

If you're looking to backup your application settings, this is the only folder of the three that's of any use to you. Can I Delete the Local, LocalLow, and Roaming Folders? Yes, but no. Deleting these folders can not only possibly break Windows, but they will also indeed remove most of your program settings.

What does Roaming folder mean? ›

The appdata/roaming folder is basically a place for Windows apps to store their configuration settings. So in Local's case, these would be things like the “name” or “domain” of a site, or if you have connected to Flywheel or WP Engine.
