NFS Files Support

"Connection refused" or the app can't mount the share

This is the #1 issue, and it's almost always the export's privileged-port requirement. iPhone and iPad apps connect from standard (non-privileged) ports, which many Linux/NAS servers reject by default. The fix depends on your server:

• Synology: Control Panel → Shared Folder → Edit → NFS Permissions → enable "Allow connections from non-privileged ports".
• Linux / Raspberry Pi / TrueNAS SCALE: add the insecure option to the export in /etc/exports, then run sudo exportfs -ra.
• QNAP: enable NFS on the shared folder and allow the access from your device's subnet.

"Access denied" once connected, or you can't open a folder

NFS has no passwords — the server checks the numeric User ID (UID) your device presents. Set the UID/GID in the app's Advanced settings to match a user on your server (the first Linux user is usually 1000/1000; on Synology it's often 1026+). Run id yourusername on the server to find it.

Recommended server setup (safest and simplest)

Export your share so every device maps to one designated user, restricted to your own network:

/srv/share  192.168.1.0/24(rw,sync,insecure,no_subtree_check,all_squash,anonuid=1000,anongid=1000)

• insecure — required for iPhone/iPad apps
• your subnet instead of * — only devices on your network can connect
• all_squash + anonuid — every client acts as one low-privilege user, so your personal account stays private and access is easy to revoke

The server isn't found automatically

Bonjour discovery only works when your NAS advertises NFS on the same network segment. If it doesn't appear, just type the server's IP address (e.g. 192.168.1.20) and tap Find Shared Folders to list its exports.

My server uses Kerberos, or it's NFSv4-only

NFS Files speaks NFSv3 — the version every NAS supports out of the box — using standard network-address access (no Kerberos). If your server is configured NFSv4-only or requires sec=krb5, enable NFSv3 for the share, or use a share that allows AUTH_SYS access.

Can I stream video, or does it download first?

Files download before they open in the preview. Large videos are cached on your device so reopening them is instant — you can clear that cache anytime in Settings → Downloaded Files.

How do I remove ads?

Open Settings → NFS Files Pro → Remove Ads. It's a one-time purchase — no subscription — and it removes all ads forever. Already purchased? Tap Restore Purchase.

Are my files private?

Yes. NFS Files talks directly to your server over your local network — your files never pass through us or any cloud. See the Privacy Policy for details.
