How to Access an SMB NAS from iPhone and iPad

Connect Fileso to an SMB share, browse NAS folders, and troubleshoot addresses, permissions and local network access.

You can browse an SMB NAS from an iPhone without copying the entire drive to the phone. Fileso connects to the share so you can find documents, preview supported files, and download the items you need. This works with a NAS or computer that already provides SMB file sharing.

Gather the connection details

Find the server’s local IP address, an account allowed to use SMB, and the share name. A share named Documents is different from the NAS administration website. Use the file-sharing account and address rather than pasting a browser login page into the connection form.

For a first connection, put the phone and NAS on the same home or office network. If iOS asks for local network access, allow it so Fileso can contact nearby devices.

Add the SMB source in Fileso

  1. Open Add Connection and choose SMB as the source type.
  2. Give the connection a recognizable name, such as Home NAS.
  3. Enter the server in Address, then supply User Name and password.
  4. Check Port in the advanced settings. Use the port configured on the server; the usual SMB port is 445.
  5. Set Path if you want to start inside a particular share. Fill in Domain only when your server requires it.
  6. Save the connection, open it, and test with a small document.

Browse first, then download a file when you need a local copy. Opening a remote folder does not make every item available offline.

When the share will not open

If the address cannot be reached, confirm that the NAS is awake and the phone is not on an isolated guest network. Try the numeric IP address if the server name does not resolve.

If login succeeds but a folder is missing, inspect the account’s share permissions. Read access does not imply upload or delete access. A successful preview followed by a failed upload often points to permissions or free space on the NAS.

Can this replace cloud storage?

An SMB share can keep files accessible inside your own network. Reaching it away from home requires a separately configured network route, such as your existing VPN. Saving an SMB connection in Fileso does not itself create remote internet access.
