Copying and Pasting Text
You can copy and paste plain text and HTML-format rich text between the client device and remote desktops and published applications. An administrator can configure this feature so that copy and paste operations are allowed only from the client system to a remote desktop or published application, or only from a remote desktop or published application to the client system, or both, or neither.
An administrator can configure the ability to copy and paste by using group policy settings that pertain to Horizon Agent for remote desktops and published applications. For more information, see Horizon Web Client Group Policy Settings section.
If you use Horizon Web Client in a Microsoft Edge 44 or Safari browser, you must click the Clipboard icon on the sidebar and use the Copy & Paste window to copy and paste text. See Use the Copy and Paste Window.
If you use Horizon Web Client in a Chrome, Microsoft Edge 81 or later, or Firefox browser, a tool tip appears when you point to the Clipboard icon on the sidebar. The tool tip explains whether the clipboard feature is available. After you allow access to the clipboard, copying and pasting from the client system to a remote desktop or published application, and conversely, is the same as copying and pasting between applications on the same system. For example, you can press Ctrl+C to copy text and press Ctrl+V to paste text. When you copy and paste rich text, the following restrictions apply.
- Image copy and paste is not supported.
- If you copy rich text from the client device and the destination is the WordPad application, only the plain text is copied and pasted.
- A Horizon administrator can use group policy settings to restrict clipboard formats during copy and paste operations. Because Horizon Web Client supports transferring only text in the clipboard, only the text filters work with Horizon Web Client. For information about clipboard format filter policy settings, see the Horizon Remote Desktop Features and GPOs document.
The clipboard can accommodate a maximum of 1 MB of data for all types of copy and paste operations. If the plain text and rich text data together use less than the maximum clipboard size amount, the formatted text is pasted. Often, the rich text cannot be truncated, so that if the text and formatting use more than the maximum clipboard size amount, the rich text is discarded, and plain text is pasted. If you are unable to paste all the formatted text you selected in one operation, you might need to copy and paste smaller amounts in each operation.
You cannot copy and paste graphics. You also cannot copy and paste files between a remote desktop and the file system on the client computer.
Note: The copy and paste feature is not supported in iOS Safari or Android devices.
Use the Copy and Paste Window
When you use Horizon Web Client in a Microsoft Edge 44 or Safari browser, you must use the Copy & Paste window to copy and paste text.
This procedure describes how to use the Copy & Paste window to copy text on the local client system to an application in a remote desktop or to a published application, and how to copy text from an application in a remote desktop or published application to the client system.
If you are copying and pasting text between published applications, or between remote desktops, you can copy and paste as you normally do. You do not need to use the Copy & Paste window.
The text in the Copy & Paste window shows one of the following messages to indicate in which direction you can copy and paste content.
- Use this panel to copy & paste content between your local client and remote desktop/application.
- Use the panel to copy & paste content from your local client to remote desktop/application.
- Use the panel to copy & paste content from your remote desktop/application to local client.
Note: The default clipboard redirection group policy setting allows you to copy only from the client system and paste into a remote desktop or published application. To be able to copy from a remote desktop or published application to the client system, a Horizon administrator must enable the group policy setting in both directions.
Prerequisites
If you are using a Mac, verify that you have enabled the setting for mapping the Command key to the Windows Ctrl key when using the key combinations to select, copy, and paste text. Click the Open Settings Window toolbar button in the sidebar and turn on Enable Command-A, Command-C, Command-V, and Command-X. If you are using a Mac, this option appears only in the Settings window.

Procedure
-
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.
-
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.
-
To save the settings, click Close.
The folder sharing settings apply to all remote desktops and published applications.
Results
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.
Use Multiple Sessions of a Published Application From Different Client Devices
When an administrator has activated multi-session mode for a published application, you can use multiple sessions of the same published application when you log in to the server from different client devices.
For example, if you open a published application in multi-session mode on client A, and then open the same published application on client B, the published application remains open on client A and a new session of the published application opens on client B. By comparison, when multi-session mode is deactivated (single-session mode), the published application session on client A disconnects and reconnects on client B.
The multi-session mode feature has the following limitations.
- Multi-session mode does not work for applications that do not support multiple instances.
- If the application session is disconnected while you are using a published application in multi-session mode, you are logged off automatically and any unsaved data is lost.
Prerequisites
An administrator must activate multi-session mode for the application pool. End users cannot modify the multi-session mode for a published application unless an administrator allows it. See Desktops and Applications in Horizon 8.
Procedure
- Connect to a server.
- Click the Settings toolbar button in the upper-right corner of the desktop and application selector window, scroll down to the Multi-Launch setting, and click Set.
- Alternatively, if you previously started a remote desktop or published application, you can click the Open Menu button in the sidebar, click Settings, and scroll down to the Multi-Launch setting. If no published applications are available to use in multi-session mode, the Multi-Launch setting is dimmed.
- Select the published applications that you want to use in multi-session mode and click OK.If an administrator has enforced multi-session mode for a published application, you cannot change this setting.
Adjusting the Sound in Remote Desktops and Published Applications
By default, sound playback is enabled for remote desktops and published applications. An administrator can set a policy to turn off sound playback. Some limitations apply to sound playback in remote desktops and published applications.
- To turn up the volume, use the sound control on the client system, not the sound control in the remote desktop.
- Occasionally, the sound might go out of sync with the video.
- In conditions of heavy network traffic, or if the browser is performing many tasks, sound quality might be reduced. Some browsers work better than others in this regard.
