Mount Drive on your computer

last updated at: Jun 30, 2026

Eigen Drive supports WebDAV (RFC 4918), so you can connect any of your drives as a network volume on macOS or Windows. Files appear in Finder or File Explorer like a local folder, so 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 now. It's 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 connects 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 in File Explorer, then choose Map network drive (in Windows 11 it is under the ⋯ menu in the toolbar).
  3. Pick a drive letter, paste the WebDAV URL for your drive into the Folder field, and tick Connect using different credentials.
  4. Click Finish, then enter your Eigen email address and app password when prompted.

Use Map network drive and paste the URL straight into the Folder field. Do not use the Add a network location wizard (the "Connect to a Web site that you can use to store your documents and pictures" link). It checks the parent folders of the address to validate it, and Eigen deliberately does not expose those, so the wizard reports the address as invalid even though the drive itself works fine.

Windows requires HTTPS for HTTP Basic authentication. Plain HTTP connections are 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 connected drive.
  • Copy and move files within the same drive.
  • Create and delete folders.
  • Read Eigen documents as folders: documents, spreadsheets, and other Eigen file types appear as folders rather than single files. You can open and copy them (handy for backups), but you can't change what's inside them from a WebDAV client.

Cross-drive moves and copies aren't supported over WebDAV. To move files between drives, download them and upload them again.

Sign in and authentication

Use your Eigen email address as the username, and the app password you generated as the password, not your main account password. If you have two-factor authentication switched on, you must use an app password; your main password won't work.

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: this usually means you used the Add a network location wizard, which cannot validate Eigen drives. Use Map network drive instead, and paste the URL into the Folder field. Also 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 documents (.eigendoc, .eigensheets, and so on) show up as folders in WebDAV listings, not as individual files. If a file is in the trash it will not appear in WebDAV listings.
