Open the house share from a Chromebook

The house folder is on the old PC. Open it from a Chromebook Files app on house Wi-Fi. You don't need a NAS app for this.

Haven't made the house folder yet? Start with a file share. Need the computer's address first? Find it on the house network. Opening from a Windows or Mac laptop? That is open the house share from a laptop. From a phone? That is open the house share from a phone. From a Linux desktop? That is open the house share from a Linux laptop. This note is the Chromebook walk: Files, then SMB file share.

Skip until the folder exists

If you never made the share, stop. That is a file share. This note assumes Samba is already serving a folder, often named photos, on the computer. The Chromebook has to be on the same house Wi-Fi. A phone hotspot will not reach it. Don't forward SMB on the router.

What this is

SMB is the language Windows, Mac, phones, and ChromeOS already use for shared folders. The Chromebook Files app can mount a Samba share without a Play Store NAS app. You type the computer's address, the share name, the Samba username, and the share password. That password is the one Samba keeps, not always the SSH login. If you forgot it, set it again in set or change the house-share password.

What you need

The computer's address, the same number you SSH to. Swap the example for yours:

smb://192.168.1.50/photos

If you don't know the number, find it on the house network. If ping fails from another laptop, start with is the computer still on? before you blame the Chromebook.

Add the share in Files

Open the Launcher. Open Files. In the top right, open the three-dot menu (More). Pick Add new service, then SMB file share. Some ChromeOS builds say Services โ†’ SMB file share. Same idea.

A window opens. Fill it in:

Leave Guest off. Tap Add. The share shows in the Files sidebar, next to Downloads and Google Drive. Open it. Copy one file in. Copy one out. That is the whole check.

The next time, that share stays in the sidebar. Stay on house Wi-Fi. Skip Guest.

If Files will not mount it

Stay on house Wi-Fi, not Guest Wi-Fi that isolates devices. Recheck the URL, the share name, and the password. If a phone or Windows laptop cannot see the folder either, Samba probably stopped, or the firewall hid it: when the house share disappeared, check the computer. If the login fails, that is the share password, not a vanished folder.

School or work Chromebooks sometimes block SMB. The policy name is around NTLM share authentication. If Add new service is missing, or every mount fails with a credentials error while a personal Chromebook works, that is an admin lock. Use a personal Chromebook, or open the folder from a phone or Windows/Mac laptop instead.

If you can see the folder but cannot drop a file in, the Linux folder owner is the usual culprit. Samba is using that same user, so that user has to own the folder:

sudo chown youruser:youruser /srv/share

Swap youruser and the path if you used a different folder. Try the Chromebook again.

What this is not

This is not a reason to buy a NAS, a Synology app, or a VPN. It is not a reason to open SMB to the internet. The share stays on the house network. A phone or a Windows laptop can open the same folder if the Chromebook is being stubborn.

What next

Prefer Windows or a Mac for big dumps? Open the house share from a laptop. On a Linux desktop: open the house share from a Linux laptop. From the couch on a phone: open the house share from a phone. Dump camera-roll photos: save phone photos to the house share. If you forgot the share password, set or change the house-share password. If the folder vanishes later, when the house share disappeared, check the computer. After the house can open it, see if the computer still has room. When you want a second copy, that is a backup of the house folder.
