By default, you can copy and paste text from your 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 your client system or between two remote desktops or applications. Supported file formats include text, images, and RTF (Rich Text Format). Some restrictions apply.
If you use the VMware Blast display protocol or the PCoIP display protocol, a Horizon administrator can set this feature so that copy and paste operations are allowed only from your client system to a remote desktop or application, or only from a remote desktop or application to your client system, or both, or neither.
Horizon administrators 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, administrators might also be able to use group policies to restrict clipboard formats during copy and paste operations or use Smart Policies to control copy and paste behavior in remote desktops. For more information, see the Configuring Remote Desktop Features in Horizon 7 document.
In Horizon 7 version 7.0 and earlier and Horizon Client 4.0 and earlier, the clipboard can accommodate 1 MB of data for copy and paste operations. In Horizon 7 version 7.0.1 and later and Horizon Client 4.1 and later, the clipboard memory size is configurable for both the server and the client. When a PCoIP or VMware Blast session is established, the server sends its clipboard memory size to the client. The effective clipboard memory size is the lesser of the server and client clipboard memory size values.
If you are copying formatted text, some of the data is text and some of the data is formatting information. If you copy a large amount of formatted text or text and an image, when you attempt to paste the text and image, you might see some or all of the plain text but no formatting or image. The reason is that the three types of data are sometimes stored separately. For example, depending on the type of document you are copying from, images might be stored as images or as RTF data.
If the text and RTF data together use less than maximum clipboard size, the formatted text is pasted. Often the RTF data cannot be truncated, so that if the text and formatting use more than the maximum clipboard size amount, the RTF data is discarded, and plain text is pasted.
If you are unable to paste all of the formatted text and images you selected in one operation, you might need to copy and paste smaller amounts in each operation.
You cannot copy and paste files between a remote desktop and the file system on your client computer.
