Transfer files
If you need to transfer files between your cloud computer and a local device, you can use built-in features such as disk mapping, the clipboard, the file transfer module, and the file migration tool, as well as third-party file transfer utilities. For Enterprise Edition cloud computers, file transfer approval and file transfer audit features are also available.
This topic uses the macOS client V7.13 and the Enterprise Edition as examples. If your experience differs, you may be using a different client or an outdated version. Upgrade to the latest version. For the Personal Edition, see Personal Cloud Computer.
Prerequisites
You have signed in to the desktop client. For more information, see Sign in to the desktop client.
You have been assigned a cloud computer. If no cloud computer appears after you sign in, contact your IT administrator to assign one to you. For more information, see Assign cloud computers to users.
Supported transfer methods
Transfer method | Supported clients | Transfer direction | Supported cloud computer OS | Best for |
File transfer module (floating ball) | All clients | Bidirectional | Windows Server, Linux Ubuntu, Kylin | File uploads and downloads |
Clipboard | Small files and text | |||
Local disk mapping | Windows client, macOS client, Android client | Large files or continuous file read/write | ||
File migration tool | Windows client or macOS client (V7.4 or later) | Local to cloud computer only | Bulk migration from local device to cloud computer |
Considerations
Operating system support — All transfer methods support the following cloud computer operating systems: Windows Server, Linux Ubuntu, and Kylin.
Network connection — All transfer methods require a stable network connection. Network interruptions may cause transfer failures.
File integrity — When you transfer large files, verify the file size after the transfer is complete to ensure data integrity.
Clipboard file size — The clipboard is best suited for small files and text. For files larger than 100 MB, use local disk mapping or transfer files through Object Storage Service (OSS) to avoid transfer interruptions or failures.
Disk mapping client support — Disk mapping is supported only by the Windows client and the Android client. The Linux client does not provide this feature, so Linux cloud computers cannot use disk mapping. This feature is also unavailable for cloud computers accessed through a web browser (web client). To transfer files between a Linux cloud computer and your local device, use the file transfer module instead.
SSH and SCP not supported — You cannot use SSH or SCP to transfer files with a cloud computer. TCP port 22 on the cloud computer is not reachable over the Internet, so SSH and SCP connections time out. To transfer files, use the file transfer module (floating ball) instead. See Method 3: File transfer module.
Transfer files
Method 1: Disk mapping
Background
Disk mapping allows you to access a local disk from your cloud computer. The available modes are:
Read-only: You can view and copy data from the local disk to the cloud computer, but you cannot modify the data.
Disable: You cannot access data on the local disk from the cloud computer.
Read/Write: You can view, copy, and modify data on the local disk from the cloud computer.
Prerequisites
The cloud computer runs Windows Server, Linux Ubuntu, or Kylin.
You connect to the cloud computer from a Windows client or Android client.
The disk mapping policy associated with the cloud computer is set to Read/Write or Read-only.
For desktop clients
V7.13or later and cloud computer imagesV2.12or later, the copy permission for disk mapping in the policy associated with the cloud computer must be set to Allow Copy from Local Disk to Cloud Computer to copy files from the mapped local disk to the cloud computer.
Disk mapping is supported only by the Windows client and the Android client. The Linux client does not provide this feature, so Linux cloud computers cannot use disk mapping. If you use a Linux cloud computer, use Method 3: File transfer module to transfer files instead.
Procedure
In your cloud computer, open the mapped local disk and then cut, copy, and paste files.
Transfer via Android client
The Android client enables local disk mapping by default. You can manage it by performing the following steps.
Open the Wuying client, log on to Enterprise Edition, and connect to the cloud computer.
After you connect to the cloud computer, tap the floating ball and select the Peripherals tab.
Under Storage Devices, you can enable or disable Auto Connect and view the status of internal storage devices.
Open This PC and select Internal Storage Device in the left-side menu to copy, paste, cut, and edit files the same way as you do with local files.
If you do not want to maintain bidirectional synchronization between the cloud computer and your phone, disable Auto Connect under Storage Devices and tap Safely Eject.
Method 2: Clipboard
Prerequisites
Supported clients: All clients.
The clipboard control rule in the policy associated with the cloud computer must allow the desired transfer direction. For example, to transfer a file from your local device to the cloud computer using the clipboard, the clipboard control rule must be set to Allow Two-way Copy or Allow Copy from Local Device to Cloud Computer.
NoteFor files larger than 100 MB, use local disk mapping or transfer files through Object Storage Service (OSS). The clipboard is best suited for small files and text.
Procedure
Cut or copy a file or folder and then paste it in the destination. You can use keyboard shortcuts (Ctrl+X, Ctrl+C, or Ctrl+V) or context menu commands to cut, copy, and paste files.
Method 3: File transfer module
Use the file transfer module in DesktopAssistant to transfer large or numerous files. This allows you to transfer files in the background and check the transfer status and progress on the File Transfer panel at any time.
Linux users can access the cloud computer through the web client and use the file transfer module.
Prerequisites
Supported clients: All clients.
The cloud computer image is V2.1.0 or later. For information about how to update the image of a cloud computer, see Manage and maintain cloud computers.

File transfer approval
Enterprise Edition administrators can enable file transfer approval for specific users or user groups in the console. After this feature is enabled, when you transfer data using the client-cloud clipboard, file migration, or file transfer, you must obtain approval from a designated approver.
Prerequisites
You connect to the cloud computer from a Windows client or macOS client (V7.13 or later).
The cloud computer image is
V2.11.3or later. For information about how to update the image of a cloud computer, see Upgrade cloud computer components and images.
Rules
The file approval feature is disabled by default for both users and user groups.
Settings for user groups have priority over settings for individual users.
If a user belongs to multiple user groups with conflicting settings, the approval requirement applies.
For security reasons, if the client version is earlier than V7.13 or the cloud computer image version is earlier than V2.11.3, enabling file approval for a user or user group automatically disables file transfer, data migration, and clipboard file transfers.
