Nextcloud は、最も広く導入されているセルフホスト型クラウド ストレージ プラットフォームです。 Dropbox や OneDrive とは異なり、Nextcloud は自宅の NAS、VPS、Raspberry Pi などの独自のサーバー上で実行します。 AnExplorer は WebDAV 経由で Nextcloud に接続し、Nextcloud モバイル アプリを必要とせずに完全なファイル管理を提供します。
Nextcloud を AnExplorer に接続する方法
Nextcloud は、次の場所で WebDAV エンドポイントを公開します。
https://your-nextcloud-server.com/remote.php/dav/files/YOUR_USERNAME/
In AnExplorer:
- Open AnExplorer and tap + in the sidebar
- Select WebDAV
- Enter your Nextcloud WebDAV URL (see format above)
- Username: your Nextcloud login
- Password: your Nextcloud password (or an app password — recommended)
The connection appears in the AnExplorer sidebar as a WebDAV bookmark.
Use an App Password (Strongly Recommended)
Nextcloud supports app-specific passwords, which let you grant AnExplorer access without exposing your main Nextcloud password. If your main password changes, only the app password needs to be regenerated.
Create an app password in Nextcloud:
- Log in to your Nextcloud web interface
- Go to Profile icon → Personal settings → Security
- Under "Devices & sessions", enter a name like
AnExplorerand click Create new app password - Copy the generated password and paste it into AnExplorer's WebDAV password field
What You Can Do
| Action | Notes |
|---|---|
| Browse all Nextcloud folders | Including shared folders and team spaces |
| Download to phone | Long-press > Copy > Paste to local folder |
| Upload from phone | Copy local file > Paste to Nextcloud WebDAV bookmark |
| Create folders | Long-press in space > New Folder |
| Delete files | Long-press > Delete |
| Move between Nextcloud and NAS | Copy from Nextcloud > Paste to SMB/FTP bookmark |
For moving files between Nextcloud and a NAS directly from AnExplorer, see the NAS connection guide. This works because AnExplorer can have both open at the same time in its sidebar.
Common Nextcloud Deployment Types
| Deployment | Nextcloud URL format |
|---|---|
| Home server (local only) | http://192.168.1.x/remote.php/dav/files /USERNAME/ |
| VPS or cloud server | https://cloud.yourdomain.com/remote.php/dav/files/USERNAME/ |
| Synology via Nextcloud package | @https://your-nas.com:PORT/remote.php/dav/files/USERNAME/ |
| Nextcloud All-in-One (Docker) | Typically https://cloud.yourdomain.com/remote.php/dav/files/USERNAME/ |
For HTTP-only (no HTTPS) connections on a local network: some Android versions require a specific setting to allow cleartext HTTP connections. If the connection fails, try adding https:// even on LAN — or set up a self-signed certificate in Nextcloud.
Nextcloud vs Nextcloud + AnExplorer vs Nextcloud App
| Nextcloud App | AnExplorer + WebDAV | |
|---|---|---|
| Photo auto-sync | ✅ | ❌ |
| File browsing | ✅ | ✅ |
| Manage NAS files alongside | ❌ | ✅ |
| Offline access | ✅ (marked files) | Downloads only |
| Archive handling (ZIP/7z) | ❌ | ✅ |
| TV/Wear OS access | ❌ | ✅ |
| Multiple cloud accounts | ❌ | ✅ |
If you also want photo auto-sync from your phone to Nextcloud, keep the Nextcloud app installed alongside AnExplorer — use Nextcloud app for sync, AnExplorer for browse and manage.
Troubleshooting
Connection refused or 404 error:
- Verify the WebDAV URL format — the
/remote.php/dav/files/USERNAME/パスは必須です - ブラウザでテストします。WebDAV URL を貼り付けます。認証プロンプトが表示されます。
401 不正:
- ユーザー名とパスワードを再確認してください
- Nextcloud で 2FA を有効にしている場合は、(メインのパスワードではなく) アプリ パスワードを使用する必要があります**
リモート接続でのパフォーマンスの低下:
- インターネット経由の Nextcloud WebDAV はローカル LAN アクセスよりも遅い
- 家庭で使用する場合、NAS 上で SMB と Nextcloud を併用すると、大きなファイルの処理が高速になります。
