Yes, Samsung Galaxy Book has Quick Share, and it's on by default

Quick Share is Samsung's built-in file-sharing tool on Galaxy Book devices. It lets you send files, photos, links, and text to nearby Samsung devices and contacts without email or cloud storage. The feature is turned on when you first set up your Galaxy Book, which means other people nearby can potentially see your device and send you files unless you change the settings.

Quick Share works over Bluetooth and Wi-Fi Direct — it doesn't need an internet connection. When someone sends you a file through Quick Share, you get a notification asking whether to accept or decline. The files land in your Downloads folder by default. The trade-off is convenience: Quick Share is fast and doesn't require passwords, but that speed comes from having the feature active and discoverable.

Key Takeaways

  • Quick Share is enabled by default on Samsung Galaxy Book, making your device visible to nearby devices unless you turn it off.
  • You can set Quick Share to receive files from contacts only, nearby devices, or turn it off entirely — each option is in Settings under Advanced Features.
  • Files received through Quick Share land in your Downloads folder with no additional security checks, so you should review what you accept.
  • Turning off Quick Share when you're not using it reduces the surface area for unwanted contact, especially on public networks.

Where Quick Share settings live on Galaxy Book

Open Settings on your Galaxy Book. Go to Advanced Features — this is usually in the left sidebar under the main settings categories. Look for Quick Share in that menu. You'll see a toggle to turn it on or off, and below that, a dropdown menu labeled Receive From.

The "Receive From" dropdown gives you three choices: Everyone, Contacts Only, or No One. "Everyone" means any device nearby can send you files. "Contacts Only" means only people in your Samsung account contacts can send to you. "No One" turns off receiving entirely — you can still send files to others, but nobody can send to you.

What each Quick Share setting actually means for your device

Everyone: Your Galaxy Book shows up on the Quick Share network with your device name visible. Anyone within Bluetooth and Wi-Fi Direct range can see it and attempt to send you files. You still get a notification and can decline, but your device is actively broadcasting. This is the default setting.

Contacts Only: Only people whose phone numbers or email addresses are in your Samsung account contacts can send you files. Your device still appears on the network, but the system checks the sender against your contact list before letting the transfer happen. This cuts down random requests but still requires you to have set up your Samsung account and synced your contacts.

No One: Quick Share stops receiving files entirely. Your device won't appear on the Quick Share network. If you need to send a file to someone else, you can still initiate the transfer from your end — this setting only blocks incoming transfers. This is the most restrictive option and the one to use if you're on public Wi-Fi or don't plan to use Quick Share.

When to change your Quick Share settings

If you work in an office, coffee shop, or any shared space where you don't want random file requests, set Quick Share to Contacts Only or turn it off. The same applies if you're traveling or at a conference. You can change it back when you get home.

If you live alone and regularly share files with family or friends who have Samsung devices, Contacts Only is a reasonable middle ground — it keeps the feature active for people you know but blocks strangers. If you never use Quick Share, turning it off entirely removes one more thing broadcasting your device on a network.

The key is that this is not a one-time choice. You can change your Quick Share setting in seconds whenever your situation changes. There's no penalty for switching between "Contacts Only" and "No One" depending on where you are.

What happens to files you receive through Quick Share

Files sent to you through Quick Share land in your Downloads folder. They arrive with no additional scanning or security checks — Quick Share doesn't run the files through antivirus or verify their source beyond checking whether the sender is in your contacts (if you have that setting on). This means you should treat Quick Share files the same way you'd treat email attachments: don't open anything from someone you don't recognize, and be cautious about executable files (.exe, .msi, .bat) even from people you know.

If you're concerned about what's in your Downloads folder, you can review it before opening anything. Right-click the file and choose Properties (Windows) or Get Info (if using a Galaxy Book with Linux) to see the file size, type, and when it arrived. If something looks wrong, delete it.

Quick Share vs. other ways to send files on Galaxy Book

Quick Share is fastest for nearby devices, but it's not your only option. You can email files, use cloud storage like Google Drive or OneDrive, or use messaging apps like Telegram or Discord. Each has different privacy and security properties. Email is slower but creates a record. Cloud storage requires an account but works across any device. Messaging apps are encrypted end-to-end on some platforms but require the recipient to have the app installed.

Quick Share wins on speed and convenience when both people are nearby and have Samsung devices. It loses if you need a record of the transfer, if the recipient doesn't have a Samsung device, or if you're on a network you don't trust. The right choice depends on what you're sending, who you're sending it to, and what matters more to you: speed or a paper trail.

Frequently Asked Questions

Can someone use Quick Share to put malware on my Galaxy Book?

Quick Share itself doesn't run files automatically — it just transfers them to your Downloads folder. You have to open the file for anything to run. The risk is the same as downloading a file from email or a website: if you open a malicious file, it can cause harm. The protection is the same too: don't open files from people you don't know, and be skeptical of executable files even from people you do know.

Does Quick Share work if my Galaxy Book is asleep?

No. Your device needs to be awake and unlocked for Quick Share to receive files. If your screen is off or the device is in sleep mode, incoming Quick Share requests will fail. This is actually a safety feature — it means someone can't send you files while your device is unattended.

Can I see who sent me a Quick Share file?

Yes. When you receive a file through Quick Share, the notification tells you the sender's device name. If you have that person in your contacts, their name appears. If not, you see only the device name. The file itself doesn't carry sender information once it's in your Downloads folder, so if you wait a while to open it, you may not remember who sent it.

What if I turn off Quick Share and someone tries to send me a file?

They'll get an error message saying your device isn't accepting Quick Share transfers. Nothing happens on your end — you won't see a notification or know someone tried. Your device straightforward won't appear on their Quick Share network.

Does Quick Share work across different Samsung devices?

Yes. Quick Share works between Galaxy Books, Galaxy phones, and Galaxy tablets as long as they're all on the same Wi-Fi network or in Bluetooth range. It also works with some non-Samsung devices that support the underlying protocol, though Samsung devices are the primary target. Check your recipient's device to confirm Quick Share is available before trying to send.
