    Drive and Photo Service:File upload feature

    Last Updated:May 26, 2026

    This topic describes the file upload feature and its related upload limits.

    Feature overview

    • Instant upload: If an identical file already exists in the cloud drive, it uploads instantly, skipping the full upload process.

    • Drag-and-drop upload: After logging on to the cloud drive, you can drag multiple local files into a specific directory to upload them.

    • Concurrent uploads: You can run up to 10 concurrent upload tasks.

    • Customizable upload speed: You can limit the network bandwidth for concurrent uploads to reduce the impact on your network.

    • Automatic retries: If an upload fails, the system automatically retries the operation to ensure it completes successfully.

    • Anonymous upload via shared links: External users can anonymously upload files to the cloud drive using a shared link.image

    • Handle file name conflicts: When uploading a file or folder that has the same name as an existing one, you can choose "Skip", "Overwrite", or "Keep Both".

      • Skip: Skips uploading the local file or folder, keeping the existing item in the cloud drive.

      • Overwrite: Replaces the existing file or folder in the cloud drive with the newly uploaded local item.

      • Keep Both: Keeps the existing item and uploads the new one, appending a date to the new item's name to differentiate them.imageimage

    FAQ

    Transfer module unavailable

    1. Download the latest version of the Cloud Drive for Enterprises (CDE) client and try uploading again. For more information, see Client download.

    2. If you already have the latest version installed, restart the client and try again.

    3. If the upload still fails, export logs and then contact us for support.

    Slow transfer speed

    Note

    Transfer speeds on the web client may be slower. For optimal performance, we recommend using the desktop client. For installation instructions, see Client download.

    • Slow upload speed on the desktop client

      If the upload speed is slow, make sure the file you are uploading is stored locally. If not, copy it to your local machine before uploading.

    • Slow speed when uploading a local file to the cloud drive

      1. Go to the Speed Test Platform to test your local network bandwidth. To ensure an accurate result, make sure no other upload tools are running.

      2. From the main interface, click your profile picture in the upper-right corner, and navigate to User Settings > Network Diagnostic Tool to perform a "Network Diagnosis".

      3. After completing the test and diagnosis, contact us for assistance.

    "Service is initializing" error

    If you receive a "Service is initializing, please try again later" error while using Cloud Drive for Enterprises (CDE), follow these troubleshooting steps:

    1. Operating system requirements

      We recommend using Windows 10 (64-bit) or later or macOS 10.15 or later.

      If you are using an older OS version, you can try using an older version of the client. However, to ensure full functionality, compatibility, and security, we strongly recommend upgrading your operating system.

    2. Loopback network check

      In the lower-left corner of the desktop, search for CMD and open Command Prompt (CMD). Run the command ping 127.0.0.1 :

      If you receive continuous replies, the loopback network is working correctly.

      If the ping fails, there may be an issue with your system or firewall configuration.

      Recommended action:

      Try temporarily disabling the Windows firewall for testing:

      1. In the search box in the lower-left corner of the desktop, search for and open "Firewall".

      2. Go to the settings for Domain network, Private network, and Public network.

      3. Turn off the firewall for each network type.

      4. Restart the cloud drive client and try the transfer again.

    3. Antivirus software blocking network access

      Some antivirus software, such as 360 Security Guard, may block the client's network connection, leading to transfer or login failures. Follow these steps to grant the client network access:

      Example using 360 Security Guard:

      1. Open 360 Security Guard

        • Launch 360 Security Guard and go to the main Network screen.

      2. Go to traffic firewall settings

        • Select "Tool Box" from the menu bar.

        • Click "Traffic Firewall" to open its settings page.

      3. Find and allow network access for the related processes

        • On the Traffic Firewall page, find the list of programs currently using the network.

        • Check the list for datatransfer.exe or EnterpriseFileManager.exe and review their network access status.

        • If either process is blocked, click the "Manage" icon next to it and select "Allow network access".

    4. If the issue persists, export logs and then contact us for assistance.

    Slow uploads from outside mainland China

    When using the service from outside the Chinese mainland, transfer speeds may be slower due to cross-border network conditions. To improve performance, you can activate Global Accelerator.

    Speed limits

    1. Cloud Drive for Enterprises (CDE) does not actively limit transfer speeds for regular, authenticated use. In high-concurrency scenarios, such as bulk distribution, the system may dynamically regulate transfer rates. If you are using the service overseas, you can activate Global Accelerator to improve performance.

    2. If you have any questions, please contact us.

    Upload auto-resume

    If a transfer is interrupted, the client automatically resumes it when you log back on to the cloud drive.

    "Waiting for retry" status

    The "Waiting for retry" status appears when an upload fails due to an error, such as a network issue.
