    Drive and Photo Service:Mounted drive

    Last Updated:Mar 09, 2026

    The mounted drive maps cloud storage to a local drive, enabling you to access, edit, and back up cloud files as if they were stored locally.

    Features

    • Two-way real-time synchronization between local and cloud storage.

    • Direct access to cloud files as a local disk, without pre-downloading.

    • Smart prefetching and on-demand downloads. For example, stream audio and video files without waiting for a full download.

    • Smart cache management with minimal local disk usage.

    • Support for both Windows and macOS.

    Limitations

    • The mounted drive does not support simultaneous editing by multiple users. For collaborative editing, use online document editing.

    • The mounted drive cannot be installed on Windows systems that run on ARM processors, such as some Microsoft Surface models that use Qualcomm Snapdragon CPUs.

    • The mounted drive is a client-side plugin and does not offer an API.

    • File access requires a stable, high-bandwidth network connection. On slow or unstable networks (such as mobile hotspots), file transfers may fail. In these situations, use the Enterprise Drive Client to download files, edit them locally, and then upload the changes back to the cloud.

    • Microsoft stopped supporting Windows 7 on January 14, 2020. Many software ecosystems have also stopped supporting Windows 7. As a result, you may be unable to use mounted disks on computers with an outdated system version. If this issue occurs, upgrade your system to Windows 11 or Windows 10.

    FAQ

    How do I fix the mounted drive installation failure on Windows?

    Note

    • Use the mounted drive on a genuine version of Windows. Issues that occur on non-official or modified systems may not be supported.

    • Always save and close files before you exit the Desktop Client to avoid data loss.

    This error is typically caused by a failed installation of the required Dokan driver.

    Troubleshooting

    First, verify if the Dokan driver is installed correctly by checking for Dokan Library in Control Panel > Programs and Features.

    image

    Based on whether the Dokan driver is installed, follow the appropriate steps below.

    Scenario 1: Dokan driver is not installed

    1. Navigate to the mounted drive plugin directory:

      C:\Users\[username]\.edm\plugins\mountapp\pkg

    2. Double-click the installer file Dokan_x64-noVC.msi to run it manually.

      image

    3. After the installation is complete, try installing the mounted drive again.

    Scenario 2: Dokan driver is installed, but the mounted drive fails to start

    1. Exit the Desktop Client completely.

    2. Manually uninstall the Dokan driver from Programs and Features.

    3. After uninstalling, you must restart the computer.

    4. After your computer restarts, open the Mounted Drive page again to trigger an automatic re-installation of the driver.

    Scenario 3: Installation fails on Windows 7 due to a missing patch

    On Windows 7, this failure may be due to the missing security patch KB4474419, which is required for driver signing.

    image

    1. Go to the Microsoft Update Catalog, download the patch that matches your OS version, and install it.

      Restart your computer for the changes to take effect.

    2. Follow the steps in Scenario 1 to manually install the Dokan driver.

    Why does the mounted drive fail with a macFUSE 'Unsupported macOS Version' error after I upgrade macOS?

    Problem

    After upgrading macOS to version 15.0 or later, opening the Desktop Client shows an Unsupported macOS Version error from macFUSE. This prevents the mounted drive from working.

    image

    Cause

    This error indicates that your current version of macFUSE is not compatible with the new version of macOS.Solution

    The solution is to update macFUSE to a compatible version. Open System Settings on your Mac, select macFUSE, and then click Update FUSE.

    After the update is complete, restart the Desktop Client to apply the changes.

    When I delete a file from the mounted drive, does it go to my local Recycle Bin or the cloud?

    Files deleted from the mounted drive are moved directly to the Enterprise Drive's Recycle Bin, not your computer's local Recycle Bin.

    • Personal space files: You can view and restore deleted files from the Recycle Bin in your personal account.

    • Team space files: Administrators can access the Recycle Bin to restore deleted team files.

    How can I check the version number of the mounted drive?

    Find the version number directly on the Mounted Drive page in the Desktop Client.

    image

    What is the correct way to upgrade the mounted drive?

    When a new version is available, the Desktop Client will prompt you to upgrade. To upgrade manually at any time:

    1. Go to the Mounted Drive page in the Desktop Client.

    2. Click Check For Update.
