Installation and Setup Guide

Copying and Pasting Text and Images
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.
Supported le 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 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 congure the ability to copy and paste by conguring group policy seings
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
Conguring Remote Desktop Features in Horizon 7 document.
If you are connected to a Horizon 7 version 7.0 or earlier server, the clipboard can accommodate 1 MB of
data for copy and paste operations. If you are connected to a Horizon 7 version 7.0.1 or later server, the
clipboard memory size is congurable 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 eective clipboard
memory size is the lesser of the server and client clipboard memory size values.
If you are copying formaed text, some of the data is text and some of the data is formaing information. If
you copy a large amount of formaed text or text and an image, when you aempt to paste the text and
image, you might see some or all the plain text but no formaing or image. The reason is that the three types
of data is 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 formaed text is pasted. Often
the RTF data cannot be truncated, so that if the text and formaing 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 the formaed 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 les between a remote desktop and the le system on the local client computer.
Configuring the Client Clipboard Memory Size
In Horizon 7 version 7.0.1 and later and Horizon Client 4.1 and later, the clipboard memory size is
congurable 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 eective clipboard memory size is the lesser of the server and client clipboard memory size
values.
To set the clipboard memory size, modify the Windows registry value HKLM\Software\VMware, Inc.\VMware
VDPService\Plugins\MKSVchan\ClientClipboardSize. The value type is REG_DWORD. The value is specied
in KB. If you specify 0 or do not specify a value, the default client clipboard memory size is 8192 KB (8 MB).
A large clipboard memory size can negatively aect performance, depending on your network. VMware
recommends that you do not set the clipboard memory size to a value greater than 16 MB.
