By default, you can copy and paste text from the iOS device 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 iOS device or between two remote desktops or applications. Supported file formats include plain text, images, and Rich Text Format (RTF). Some restrictions apply.
A Horizon administrator can set this feature so that copy and paste operations are allowed only from the iOS device to a remote desktop or application, or only from a remote desktop or application to the iOS device, or both, or neither.
Data that you copy to the clipboard is copied to the clipboard on the remote desktop when you log in to the remote desktop. If you are logged in to a remote desktop, data that you copy to the clipboard on the remote desktop is copied to the clipboard on the iOS device. If RTF data contains images, the images are lost when Horizon Client synchronizes the RTF data in the clipboard on the remote desktop with the data in the clipboard on the iOS device.
Horizon administrators can configure copy and paste behavior by setting group policies that pertain to Horizon Agent, including changing the clipboard size. The default clipboard size is 1 MB. The clipboard can accommodate up to 16 MB of data. Depending on the Horizon server and agent version, administrators might also use group policies to restrict clipboard formats during copy and paste operations, or use Smart Policies. For information, see the Configuring Remote Desktop Features in Horizon 7 document.
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 the formatted text you selected in one operation, you might need to copy and paste smaller amounts in each operation.
You might not be able to copy and paste a certain image, even though it does not exceed the clipboard size. This problem occurs when Horizon Client converts the image to PNG format and the PNG image exceeds the clipboard size. Horizon Client converts all images to PNG format during the copy and paste operation.
