WUYING Terminal:Transfer files

Last Updated:Nov 24, 2025

You can transfer files between a cloud computer and an on-premises device using third-party file transfer tools, or using the built-in features of Alibaba Cloud Workspace for convenient file transfers, such as disk mapping, the clipboard, the file transfer module, and the file migration tool. Elastic Desktop Service Enterprise also supports file transfer approval and file transfer auditing.

Important

This topic uses the macOS client V7.13 and the Enterprise Edition as an example. If your experience differs from the description in this topic, you may be using a different client or an outdated version. Upgrade to the latest version.

Prerequisites

  • You have logged on to the desktop client. For more information, see Log on to a desktop client.

  • You have been assigned a cloud computer. If no cloud computer is available after you log on, contact your IT administrator to have one assigned to you. For more information, see Assign cloud computers to users.

Transfer files

Method 1: Transfer files using disk mapping

Background information

Disk mapping maps a disk on your on-premises device to a disk on the cloud computer. This lets you access the local disk data from the cloud computer. Disk mapping supports the following policies:

  • Read-only: Allows you to view and copy data from the local disk on the cloud computer, but not modify it.

  • Disable: Blocks access to the local disk from the cloud computer.

  • Read/Write: Allows you to view, copy, and modify the local disk data from the cloud computer.

Prerequisites

  • The cloud computer runs a Windows operating system.

  • The connection to the cloud computer is established from a Windows client or a macOS client.

  • The disk mapping policy specified in the policy associated with the cloud computer is set to Read/Write or Read-only.

    Guide for EDS Enterprise administrators

    1. Log on to the Elastic Desktop Service Enterprise console.

    2. In the left-side navigation pane, choose Operation & Maintenance > Policies.

    3. In the upper-left corner of the top navigation bar, select a region.

    4. On the Policies page, find the policy that is associated with the cloud computer and click Change Policy in the Actions column.

      Note

      If a cloud computer is currently associated with the system policy system-all-enabled-policy, an administrator must create a custom policy in the Elastic Desktop Service Enterprise console and associate it with the cloud computer because the system policy cannot be modified. For detailed instructions, see Create a custom policy and Change an associated policy.

    5. On the Modify Policy page, choose Peripheral Control > Disk Mapping in the navigation pane on the left. In the right pane, select Read/Write or Read-only.

  • For desktop client version 7.13 or later and cloud computer image version 2.12 or later, the copy permission specified in the associated policy must be set to Allow Copy from Local Device to Cloud Computer. This permission is required to copy files from the mapped local disk to the cloud computer.
