By default, you can copy and paste text from the local client system to a remote desktop or application. If a Horizon administrator enables the feature, you can also copy and paste text from a remote desktop or application to the client system or between two remote desktops or applications.
You can copy and paste plain text only. Images and RTF (Rich Text Format) are not supported.
A Horizon administrator can configure this feature so that copy and paste operations are allowed only from the client system to a remote desktop or application, or only from a remote desktop or application to the client system, or both, or neither.
A Horizon administrator can configure the ability to copy and paste by configuring group policy settings that pertain to Horizon Agent. Depending on the Horizon server and agent version, an administrator might also be able to use group policies to restrict clipboard formats during copy and paste operations or use Smart Policies to control the copy and paste behavior in remote desktops. For more information, see the Configuring Remote Desktop Features in Horizon 7 document.
The clipboard can accommodate 64 K of data for copy and paste operations. If you try to copy more than the maximum clipboard size, the text is truncated.
You cannot copy and paste files between a remote desktop and the file system on the local client computer.
