By default, you can copy and paste plain text and HTML-format rich text from the client device to a remote desktop or published application.

You can also copy and paste plain text and HTML-format rich text from a remote desktop or published application to the client device if a Horizon administrator enables this feature.

A Horizon administrator can configure the copy and paste feature so that copy and paste operations are allowed only from the client device to a remote desktop or published application, or only from a remote desktop or published application to the client device, or both, or neither.

When you copy and paste images and rich text, the following restrictions apply.

  • If the clipboard source is a Google app, such as Google Docs, you can copy and paste images only when the client device can access the Google website.
  • If you copy an image and rich text (or plain text) together from the client device, and the destination is an application that supports only rich text, such as WordPad, the image is discarded and only the text is copied and pasted. If the destination application supports HTML/XML-format rich text, such as Microsoft Word, this restriction does not apply.
  • A Horizon administrator can use group policies to restrict clipboard formats during copy and paste operations. The clipboard format filter policies for Microsoft Office Chart and Smart Art data and Microsoft Text Effects data is not supported. For information about clipboard format filter policies, see the Configuring Remote Desktop Features in Horizon document. Using Smart Policies to control the copy and paste behavior in remote desktops is not supported.

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 maximum clipboard size, 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.
