Abstract: System and methods are provided for improved directory enumeration on shared client directories in virtual desktops. A merged I/O request containing multiple expected I/O requests for enumerating a directory can be produced on the virtual desktop. The merged I/O request can be conveyed to the client device and a merged I/O response containing multiple I/O responses to the expected I/O requests can be received from the client device. The received I/O responses can be stored in cache memory on the virtual desktop and used to respond to subsequent queries for enumerating the directory on the virtual desktop.

Abstract: System and method are described for copying and pasting files and folders between a client and a virtual desktop via clipboard redirection. A virtual desktop session can be established by the client on the virtual desktop. The user can copy a file or folder to the virtual desktop clipboard and a path corresponding to the file or folder can be stored in the virtual desktop clipboard in a path list. When the user ungrabs the agent or switches focus out of the virtual desktop to the client, the path list can be transferred to the client device and set into the client clipboard. Subsequently, a request can be received in the client device to paste the copied file or folder to a target location in the client device. In response to the request, the client device can retrieve the contents of the copied file or folder from the agent and the contents can be placed in the target location to complete the paste operation.
