With the client drive redirection feature, you can share folders or drives on the local client system with remote desktops and published applications.

Shared drives can include mapped drives and USB storage devices.

The client drive redirection feature has the following limitations.

  • Using the Windows registry key settings ForcedByAdmin, default shares, and permissions to configure client drive redirection are not supported.

  • The TCP and UDP side channels are not supported. If the agent machine is configured to use either of these side channels, you cannot use the client drive redirection feature.

  • User Environment Manager policies are not supported.

  • Network recovery is not supported. You cannot use client drive redirection after network reconnection unless you disconnect the session and connect again.

  • You can use the client drive redirection feature with only one remote session at a time. Multiple remote sessions are not supported.

  • You cannot change properties for shared folders or files in the remote desktop.


To share folders and drives with a remote desktop or published application, a Horizon administrator must enable the client drive redirection feature. This task involves installing Horizon Agent 7.4 or later and enabling the agent Client Drive Redirection option. It can also include setting policies to control the client drive redirection behavior. For more information, see the Configuring Remote Desktop Features in Horizon 7 document.


  1. Click the Settings toolbar button in the upper-right corner of the desktop and application selector window and turn on the Enable folder sharing option in the Settings window.
  2. To select a specific folder or drive to share, click Select, click Add, browse to and select the folder or drive, and click OK.

    You can add multiple folders and drives, but you can select only one item at a time. You can remove a folder or drive by clicking the X next to its name in the Folder Sharing dialog box.

  3. To save the settings, click OK.

    The folder sharing settings apply to all remote desktops and published applications.


In a remote desktop, a network location appears for each folder and drive that you shared. For example, if you shared a folder named test1, the test1(Z:) network location might appear in the remote desktop. A device also appears for each shared folder and drive. The device name format is folder on Horizon, for example, test1 on Horizon.

In a published application, you can select File > Open or File > Save As, if applicable, and navigate to the shared folder or drive.
