With Horizon Agent 7.9 and later, you can drag and drop files, folders, text, rich text, and images between the client system and remote desktops and published applications. With earlier Horizon Agent versions, you can drag and drop text, rich text, and images from the client system to a remote desktop through clipboard redirection, and you can drag and drop files from the client system to a published application through file association.
Depending on the Horizon Agent version, a Horizon administrator can use certain group policy settings or Smart Policies to configure drag and drop behavior. For complete information about configuring the drag and drop feature, see the Configuring Remote Desktop Features in Horizon 7 document for your Horizon 7 version.
