Transfer Files from Android to NAS — Connect Your Phone to Home Storage
A NAS (Network Attached Storage) is a dedicated home server — essentially a hard drive rack with a network port. It's where photos, videos, backups, and media libraries live for home and small business users. Android phones don't come with a file manager that connects to NAS devices out of the box, but AnExplorer does.
AnExplorer supports SMB (Windows file sharing), FTP/FTPS, and WebDAV — the three protocols every major NAS brand supports. Connect once, save the connection, and your NAS appears as a persistent drive in AnExplorer's sidebar.

Method 1: SMB — Best for Regular Use
SMB (Server Message Block) is the standard Windows file sharing protocol and the fastest method for home NAS access. It appears as a persistent drive in AnExplorer and survives app restarts.
Enable SMB on Your NAS
Synology DiskStation:
- Open DSM web interface → Control Panel
- Go to File Services → SMB
- Enable SMB service → click Apply
- Note the SMB path:
\\NAS-NAMEor\\192.168.x.x - Create a shared folder if you haven't already: Control Panel → Shared Folders
QNAP:
- Open QNAP admin interface → Control Panel
- Network & File Services → Win/Mac/NFS/WebDAV
- Enable Samba (Windows File Sharing) → Apply
WD My Cloud: SMB is enabled by default. Just find the IP address from your router's device list or the WD My Cloud dashboard app.
Connect AnExplorer to NAS via SMB
- Open AnExplorer on your Android phone
- In the left sidebar, tap Network → Add Network Storage
- Select SMB / Windows Share
- Enter the NAS IP address:
192.168.1.x(find this in your router's connected devices) - Enter your NAS username and password (the account you use for DSM/QNAP admin)
- Select the shared folder from the dropdown, or type it manually
- Tap Connect → the share appears in AnExplorer's sidebar
Save the connection: AnExplorer saves the connection permanently — next time you open the app on your home Wi-Fi, the NAS is instantly accessible without re-entering credentials.
Copy Files to NAS
- Open Internal Storage in AnExplorer
- Navigate to photos, videos, or documents
- Long-press to select files (or tap a folder to select everything)
- Tap Copy from the toolbar
- In the sidebar, tap your NAS share
- Navigate to the destination folder on the NAS
- Tap Paste — files transfer at LAN speed (typically 40–100 MB/s over 5 GHz Wi-Fi)
Method 2: FTP — Precise Control, Works Everywhere
FTP works when SMB is blocked (e.g., on some routers with SMB disabled for security), and it's the most universal protocol — every NAS supports FTP.
Enable FTP on Your NAS
Synology: Control Panel → File Services → FTP → Enable FTP service QNAP: Control Panel → Network & File Services → FTPWD My Cloud: Settings → Network → FTP → Enable
Connect AnExplorer via FTP
- AnExplorer → Network → Add FTP Connection
- Fill in:
- Host: Your NAS IP (e.g.,
192.168.1.100) - Port: 21 (standard FTP) or 990 (FTPS)
- Username / Password: your NAS credentials
- Host: Your NAS IP (e.g.,
- Tap Connect → NAS files appear in AnExplorer
For FTPS (secure FTP with TLS), select FTPS as the protocol — your NAS must have FTPS enabled (Synology DSM supports this under FTP → FTPS settings).
Method 3: WebDAV — Best for Remote (Over Internet) Access
WebDAV works the same as SMB or FTP for local network use, but it also works when you're away from home — connecting over the internet to your NAS if you've set up port forwarding or use a VPN.
Enable WebDAV on Your NAS
Synology: Package Center → install WebDAV Server → open it → enable HTTP (5005) or HTTPS (5006) QNAP: Control Panel → Network & File Services → WebDAV
Connect AnExplorer via WebDAV
- AnExplorer → Network → Add WebDAV Connection
- Enter:
- URL:
http://192.168.1.100:5005(local) orhttps://yournas.synology.me:5006(remote with DDNS) - Username / Password: NAS credentials
- URL:
- Connect — the NAS file system appears
Auto-Backup Phone Photos to NAS
Instead of manually copying, you can set up automatic photo backup from your phone to the NAS:
Synology Photos (recommended for Synology):
- Install the Synology Photos package on your NAS
- Install the Synology Photos app on your Android phone
- It auto-syncs your camera roll to the NAS over LAN or internet
Manual with AnExplorer (all NAS brands):
- Set AnExplorer's SMB connection to the NAS as a permanent mount
- Periodically select
/DCIM/Cameraon your phone → Copy → Paste to NAS photos folder - For automation, use Automate (Android app) or Tasker to trigger AnExplorer file operations on schedule
Transfer Large Files — Speed and Tips
Over a 5 GHz Wi-Fi connection to a NAS via SMB or FTP, expect:
- 40–80 MB/s for most home NAS devices (depends on NAS drive speed and Wi-Fi)
- A 50 GB photo library takes roughly 10–20 minutes
- 4K video files (4–20 GB each) copy in 1–5 minutes
Tips for large transfers:
- Keep your phone screen on and plugged in — battery saver modes can throttle network activity
- Use FTP for very large batch transfers — it has lower overhead than SMB for pure throughput
- Run transfers when your home network is idle (not streaming 4K video simultaneously)
- Use Gigabit Ethernet on the NAS side — the bottleneck is usually the NAS disk speed or the phone's Wi-Fi, not the NAS's network port
Access NAS from Anywhere (Remote Access)
For accessing your NAS files from outside home (e.g., at work, on mobile data):
Option 1: VPN
- Set up VPN on your router or NAS (Synology has built-in OpenVPN server; QNAP has QVPN)
- Connect to home VPN from Android using OpenVPN for Android or WireGuard
- Once connected, your phone is on your home network — open AnExplorer and connect to NAS normally
Option 2: NAS DDNS URL with WebDAV HTTPS
- Enable DDNS in your NAS (Synology: Control Panel → External Access → DDNS)
- Use a hostname like
yourname.synology.me - Enable WebDAV HTTPS on port 5006
- In AnExplorer, add WebDAV connection:
https://yourname.synology.me:5006 - Access from anywhere with internet
Troubleshooting
"SMB connection failed" or "Network error"
- Verify the NAS IP address — check your router's connected device list for the most current IP
- Confirm SMB is enabled on the NAS (common mistake: SMB disabled or SMB1 enforced on an older NAS)
- Check if your Android device and NAS are on the same network segment (not a guest network vs main network)
- Try FTP as an alternative — if FTP works but SMB doesn't, it's the SMB configuration
Files transfer slowly (under 5 MB/s)
- Check Wi-Fi band — 2.4 GHz tops out at ~50 Mbps (6 MB/s); 5 GHz can reach 500+ Mbps
- Check NAS disk type — WD Red HDDs write at ~80–120 MB/s max; SSDs are faster
- FTP usually outperforms SMB for pure file transfer throughput — try FTP if SMB is slow
NAS doesn't show available shares
- After entering the NAS IP in SMB settings, wait a moment for AnExplorer to query available shares
- If shares don't load, enter the share name manually (e.g.,
homes,photo,video) - Ensure your NAS account has permission to access the share (check share permissions in DSM/QNAP admin panel)
