Connect Drive on Android with DAVx⁵

DAVx⁵ is a free, open-source WebDAV client for Android. Once a WebDAV mount is added, your TrekMail Drive appears as a storage location in any file-manager app that supports Android's Storage Access Framework — Files by Google, Solid Explorer, Total Commander, and most others.

Verified against the official DAVx⁵ manual at manual.davx5.com/webdav_mounts.html.

Before you start

You need a device password. Sync apps get their own one-time password, separate from your dashboard login.

1. Open Sync devices in your TrekMail dashboard.
2. Click + Add new device.
3. Name it (e.g. Pixel — DAVx⁵).
4. Leave View files and Edit files checked.
5. Click Generate password and copy the password (dsync_...).

Tip: paste the password into your password manager on your phone before continuing — typing a long random string on a touch keyboard is painful.

Install DAVx⁵

DAVx⁵ is available in two places:

• F-Droid (free): F-Droid listing — open-source, no cost.
• Google Play (paid, supports the developer): Play Store listing.

Either works; same code, same features. F-Droid is the official open-source channel; the Play version is a paid copy that helps fund development.

Add the WebDAV mount

DAVx⁵ keeps WebDAV file storage in its own section (the main DAVx⁵ screen is for calendar/contact sync — your Drive lives under Tools).

1. Open DAVx⁵.
2. Tap the navigation drawer (the ☰ menu icon, top-left).
3. Pick Tools → WebDAV mounts.
4. Tap the + floating action button (bottom-right).
5. On the Add WebDAV mount screen, fill in:
   • Display name: something memorable, e.g. TrekMail Drive.
   • WebDAV URL: paste the Drive server URL from the Sync devices page on the dashboard. It looks like https://drive.YOUR-DOMAIN/dav/files/account/ — keep the trailing slash.
   • Username (optional): your TrekMail account email.
   • Password (optional): the device password (dsync_...).
6. Tap Add mount (or Mount on older versions).

DAVx⁵ verifies the connection and registers the mount as an Android storage provider.

Browse Drive from a file manager

DAVx⁵ itself doesn't have a file-browser UI — it exposes Drive through Android's Storage Access Framework so any compatible file-manager app can access it:

1. Open your file manager (e.g. Files by Google).
2. Tap the menu (☰) or Browse.
3. Look for the display name you chose (e.g. TrekMail Drive) under storage locations. On Files by Google it lives under Browse → Other storage.
4. Tap to open. Your Drive folders and files appear.

You can now:

• Tap a file to open it in the default app.
• Long-press → Move/Copy to move between Drive and local storage.
• Long-press → Share to upload from another app to Drive.
• Upload from camera / share sheet — pick TrekMail Drive as the destination from any app's share menu.

DAVx⁵ supports random-access streaming, so you can play a large video or audio file directly from Drive without downloading it first.

Battery and data usage

DAVx⁵ is friendly with battery and data:

• It does not download all files automatically — only when you open them.
• Multiple WebDAV mounts can run simultaneously without extra background drain (it's on-demand).
• Uploads use Android's Storage Access Framework, which doesn't run in the background — you have to keep the file-manager app in the foreground for large transfers.

Troubleshooting

• "Authentication failed" — use the device password (dsync_...), not your dashboard password. Re-generate if it still fails.
• "Couldn't find any resources at this address" — check the URL carefully: https://, no extra slashes, trailing slash present.
• Drive doesn't appear in Files by Google — Files by Google sometimes hides WebDAV mounts. Try Solid Explorer or Total Commander instead, or update Files by Google.
• Uploads cancel midway — Android killed the file-manager app to save memory. Keep it in the foreground for large uploads.
• 507 Insufficient Storage — your Drive pool is full. Empty the trash or resize your add-on.
