Advanced WebDAV with rclone and Mountain Duck

last updated at: Jun 8, 2026

Eigen Drive supports WebDAV, and the built-in WebDAV client in Finder or File Explorer works. On large folders, though, Finder can be slow and caches file metadata aggressively. rclone and Mountain Duck are two well-regarded alternatives that handle those cases better. Both use exactly the same connection details as the built-in client.

Before you start

You need two things from the Integrations page in Space before you configure either tool:

  • Your WebDAV URL. Under the WebDAV (Drive sync) heading, each drive you have access to is listed with its own URL. The format is:

    https://<your-eigen-host>/webdav/<ownerId>/<mountId>/

    Copy the URL for the drive you want to connect. If you have multiple drives, you'll set up a separate connection for each one.

  • An app password. Scroll down to App passwords. In the Name field, type a label such as rclone or Mountain Duck, then click Generate. Copy the password straight away. It is shown only once.

Your username for both tools is the email address shown on the same page under WebDAV (Drive sync).

Connect with rclone

rclone is a free, command-line tool that works on macOS, Windows, and Linux. It can mount your drive as a local folder, sync files to and from it, or copy it to another location for backups.

To add a new remote, run:

rclone config

When prompted, choose to add a new remote and select WebDAV as the storage type. Set:

  • URL: paste the WebDAV URL you copied from the Integrations page.
  • Vendor: choose Other.
  • User: your Eigen email address.
  • Password: when rclone asks for a password, enter the app password you generated.

Once configured, you can mount the remote as a local folder:

rclone mount eigenDrive: /path/to/mountpoint --vfs-cache-mode full

Replace eigenDrive with the name you gave the remote, and /path/to/mountpoint with an empty folder on your computer. The --vfs-cache-mode full flag caches files locally so that desktop apps can open and save them normally.

On macOS, rclone requires FUSE-T (free) to create the mount point. On Windows, it requires WinFsp (also free).

Eigen document files (such as .eigendoc or .eigensheets) appear as folders in the mount. You can read and copy them, but you cannot edit their contents from the mount. To work on a document, open it in the browser.

Connect with Mountain Duck

Mountain Duck is a commercial app for macOS and Windows that mounts WebDAV drives in Finder and File Explorer using the operating system's native file provider. It handles reconnects automatically and avoids the metadata caching issues that affect the built-in Finder WebDAV client.

To add a new connection, open Mountain Duck and create a new WebDAV (HTTPS) bookmark. Enter:

  • The server hostname from your WebDAV URL (the part after https:// and before the first /).
  • The path (everything after the hostname, starting with /webdav/).
  • Your Eigen email address as the username.
  • The app password you generated as the password.

Save the bookmark and connect. The drive appears in Finder or File Explorer.

Use rclone for backups

rclone is particularly useful for backing up your Eigen drives to another location. To copy everything from a drive to a local folder:

rclone copy eigenDrive: /path/to/local/backup

To keep a local folder in sync with the remote (adding new files and removing deleted ones):

rclone sync eigenDrive: /path/to/local/backup

Both commands copy Eigen document files as folders, preserving their full contents.
