Mount Drive on your computer

Updated 2026-05-20

Eigen Drive supports WebDAV (RFC 4918), so you can mount any of your drives as a network volume on macOS or Windows. Files appear in Finder or File Explorer like a local folder — you can open, edit, and save them without going through the browser.

Before you start

You need an app password to connect. App passwords are separate credentials you create specifically for external clients. They work even when two-factor authentication is enabled, and you can revoke them at any time without changing your main password.

To create one, open the Integrations page in Space, scroll to App passwords, enter a name (e.g. "Finder" or "My laptop"), and click Generate. Copy the password — it is only shown once.

The same page lists the WebDAV URL for each of your drives. The URL format is:

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

Connect on macOS (Finder)

  1. In Finder, open Go → Connect to Server (⌘K).
  2. Paste the WebDAV URL for your drive and click Connect.
  3. Choose Registered User, enter your Eigen email address as the username, and the app password you generated as the password.
  4. Click Connect. The drive appears under Locations in the Finder sidebar.

Finder's built-in WebDAV support works but can be slow on large folders and caches metadata aggressively. For better performance, consider Mountain Duck (commercial) or rclone (free, command-line).

Connect on Windows (File Explorer)

Windows mounts WebDAV drives through the WebClient service.

  1. Make sure the WebClient service is running. Open Services (services.msc), find WebClient, and set its startup type to Automatic if it is not already running.
  2. Open This PC, click Map network drive in the toolbar (or from the Computer menu).
  3. Click Connect to a Web site that you can use to store your documents and pictures, then follow the wizard.
  4. Enter the WebDAV URL for your drive, then your Eigen email and app password when prompted.

Windows requires HTTPS for HTTP Basic authentication — plain HTTP connections will be rejected. There is also a 50 MB default upload size limit; large files may fail unless the registry setting FileSizeLimitInBytes under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters is increased.

What you can do over WebDAV

  • Open and save files — most desktop apps (Word, Excel, TextEdit, and so on) can open files directly from the mounted drive.
  • Copy and move files within the same drive.
  • Create and delete folders.
  • Read Eigen documents as folders — .eigendoc, .eigensheets, and other Eigen file types appear as folders containing a data.db file and a media/ subfolder. You can read and copy these (useful for backups), but writing inside them is blocked.

Cross-drive moves and copies are not supported over WebDAV — you need to download and re-upload to move files between drives.

Sign in and authentication

Use your Eigen email address as the username. Use the app password you generated on the Integrations page as the password — not your main account password. If your account has two-factor authentication enabled, only app passwords work; the primary password fallback is disabled when 2FA is on.

Troubleshooting

Drive does not appear after connecting on macOS: check that the URL ends with a /. Finder sometimes drops the trailing slash.

"The folder you specified does not appear to be valid" on Windows: confirm the WebClient service is running and that the URL uses https://, not http://.

401 Unauthorized: double-check the app password was copied correctly. Passwords are only shown once; if you missed it, delete it from the Integrations page and generate a new one.

Files or folders are missing: Eigen containers like .eigendoc show up as folders. If a file is in the trash it will not appear in WebDAV listings.
