You can copy and paste plain text and HTML-format rich text between the client device and remote desktops and published applications. 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 published application, or only from a remote desktop or published application to the client system, or both, or neither.

A Horizon administrator can configure the ability to copy and paste by using group policy settings that pertain to Horizon Agent for remote desktops and published applications. For more information, see HTML Access Group Policy Settings.

When you copy and paste rich text, the following restrictions apply.
  • Image copy and paste is not supported.
  • If you copy rich text from the client device and the destination is the WordPad application, only the plain text is copied and pasted.
  • Rich text copy and paste is not supported when you use HTML Access on an Internet Explorer (IE), Microsoft Edge, or Safari browser. You must use the Copy & Paste window. See Use the Copy and Paste Window.
  • A Horizon administrator can use group policy settings to restrict clipboard formats during copy and paste operations. Because HTML Access supports transferring only text in the clipboard, only the text filters work with HTML Access. For information about clipboard format filter policy settings, see the Configuring Remote Desktop Features in Horizon 7 document.
If you are using HTML Access with a Chrome or Firefox browser, refer to the following tips when using the clipboard feature.
  • After you connect to a remote desktop or published application for the first time, the Clipboard User Guide dialog box appears. To dismiss the dialog box and never see it again, click OK.
  • By default, the Clipboard icon on the sidebar is selected and appears grey.
    • If the Clipboard icon is selected, when you copy text from a remote desktop or published application, a dialog box appears to ask for your confirmation to copy the text to the local client system's clipboard. Click OK.
    • If the Clipboard icon is deselected, the confirmation dialog box does not appear when you copy text from the remote desktop or published application to the local client system's clipboard.
  • If you move your mouse over the Clipboard icon on the sidebar, a tooltip explains how the clipboard feature works.

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 the maximum clipboard size amount, 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.

You cannot copy and paste graphics. You also cannot copy and paste files between a remote desktop and the file system on the client computer.

Note: The copy and paste feature is not supported in iOS Safari or Android devices.
