Use a USB data cable for the most dependable transfer that is genuinely offline. Unlock the Android phone, connect it to Windows, choose File transfer in the phone’s USB notification, and copy files in Windows’ file-transfer window. If you need to work without a cable but have a local Wi-Fi network (or can create a phone hotspot), Google Quick Share can send files directly between nearby devices. Microsoft Phone Link is useful when it is already configured, but its account, version, Wi-Fi and optional mobile-data requirements make it a less certain choice for a completely internet-free transfer.

Choose the method that fits your connection

“No internet” can mean two different things. A USB cable needs no network at all. Wireless methods can also work without internet access, but they still need a local connection between the phone and PC. A Wi-Fi router may provide a local network even when its internet service is down; a phone hotspot can create another local network when the existing one prevents device-to-device communication.

Also decide whether you are avoiding only internet service or cellular data as well. A local router with its broadband connection unplugged can still connect devices, while a phone hotspot may keep cellular data active. If cellular usage matters, USB is the clearest choice.

No official source in the documented procedures publishes a comparative transfer-speed benchmark. Choose based on the connection and setup you have rather than an assumed speed advantage. USB is also the least dependent on app versions, discovery settings and account pairing, so it is a sensible fallback when a wireless method is not immediately visible.

Method 1: Transfer files with a USB cable

USB is the only method here that does not require Bluetooth, Wi-Fi, Ethernet, an account or a local network. It is therefore the preferred route when the computer is offline, the network is unavailable, or you need the fewest moving parts. It gives you folder-level access to the phone’s available storage instead of requiring you to select each item through a sharing interface.

Before you connect

• Use a USB cable that supports data transfer. Some cables are designed only for charging.
• Check that the plugs match the ports on both devices. The required connector combination varies by phone and computer.
• Unlock the Android phone before changing its USB mode.
• Make sure the destination has enough free storage for the items you plan to copy, especially when moving videos or a large folder.

Do not infer data capability from the fact that a cable charges the phone. Google warns that not all USB cables transfer files. If a cable came with a charger or another accessory, check its stated data-transfer support rather than assuming every cable with the right-shaped plug is equivalent.

Step-by-step USB transfer

1. Unlock the Android device.
2. Connect it to the Windows computer with the data-capable USB cable.
3. On the phone, open the notification that says Charging this device via USB.
4. Under Use USB for, select File transfer.
5. Open the file-transfer window that appears on Windows. In many installations this is a File Explorer window showing the phone and its storage.
6. Browse to the relevant folder and drag or copy files between the computer and the appropriate phone folder. Camera pictures are commonly in a camera folder, while downloaded files may be in a downloads folder; folder names can vary by device and app.
7. Allow the copy operation to finish. For a large batch, keep the phone connected and unlocked until Windows reports completion.
8. When the copy is complete, eject the Android device from Windows, wait for the safe-removal indication, and then unplug the cable.

You can transfer in either direction: copy from the phone to Windows to make a local backup, or copy from Windows to a folder on the phone. Afterward, open a few destination files and compare the number of items before deleting originals. A completed copy notification is useful, but checking the actual files protects against an interrupted operation.

The USB notification may return to charging-only mode after the phone is disconnected or the screen is locked. Set File transfer again each time Windows does not show the phone’s storage.

If Windows does not show the phone

• Nothing happens: the cable may be charge-only, damaged or loosely connected. Re-seat both ends and try another known data-capable cable.
• The phone only charges: unlock it and select Charging this device via USB followed by File transfer. Do not assume a charging icon means data is available.
• The phone appears but folders are empty: keep the phone unlocked, confirm the USB mode is still File transfer, and reopen or refresh the Windows file-transfer window.
• The connector does not fit: use a cable whose connectors match the actual ports on the phone and PC. Do not force a plug or rely on an adapter unless it supports data.
• Copying stops: reconnect only after Windows has finished the current operation. For important files, verify that the destination file opens before deleting the original.
• The phone disappears during copying: check that the cable is firmly seated at both ends and avoid moving the phone while the operation is active. Reconnect and repeat only the files that did not arrive.

USB is a file-access connection, not a cloud transfer. Files move directly between the phone’s storage and the computer, so no internet service is involved.

Method 2: Use Google Quick Share over a local connection

Quick Share provides a cable-free way to send images, videos and documents between nearby Android devices and Windows computers. Google says shared files are encrypted, and an incoming request normally requires the recipient to approve it. Google Android Help states, “When you share files, they’re encrypted.” Android 6.0 and later includes Quick Share according to Google’s product information.

Install the correct Windows app

• On a non-Samsung Windows PC, install the Google Quick Share app.
• On a Samsung PC, use Samsung’s Quick Share app from the Microsoft Store instead.

The Windows requirements listed by Google are 64-bit Windows 10 or later. ARM-based PCs require Windows 11 or later. Android 6.0 or later is listed for the phone. If the computer is an ARM-based model, check that it meets the Windows 11 requirement rather than treating the general Windows 10 listing as sufficient.

Quick Share’s local-network requirements

Google’s help instructions require Bluetooth to be on for both devices, Wi-Fi or Ethernet to be enabled, and both devices to be connected to the same network. This does not mean files are uploaded to the internet: the requirement is a path for the nearby devices to discover and communicate with each other. Internet service can be unavailable while the local network remains usable.

Keep the devices within about 5 metres (16 feet), the distance stated on Google’s Quick Share for Windows product page. Discovery and transfer can still be affected by walls, radio interference, Windows permissions or network isolation. A guest, hotel, school or office network may intentionally prevent connected devices from contacting one another even though web browsing works.

Send files from Windows to Android

1. Open Quick Share on the Windows PC.
2. Select files or drag them into the Quick Share window. The Windows workflow supports selecting or dragging files and folders.
3. Choose the visible Android device.
4. Watch the phone for the incoming request and have the recipient approve it. Devices signed in to the same Google Account may accept their own transfer automatically.
5. Wait for the transfer to finish before closing Quick Share or disconnecting the phone from the local network.

Use a descriptive destination or batch selection where practical, then confirm the received items on the phone. Approval is a deliberate safety step, so a device that is nearby may remain listed without receiving anything until its request is accepted.

Send files from Android to Windows

1. Open the file, photo or document on the Android phone and use its Share control.
2. Choose Quick Share, then select the Windows computer shown as an available device.
3. On Windows, set Quick Share’s visibility so the PC can receive the request.
4. Accept the request on the computer.
5. Find received files in the Quick Share folder under Downloads, the location Google documents for Windows receipts.

If you cannot find an item afterward, check the Windows Downloads folder and then its Quick Share subfolder. Do not assume the file was saved to the same folder from which you selected it.

When the Wi-Fi network blocks Quick Share

Some office, school, hotel and guest networks allow internet access but prevent devices from contacting one another. Google’s documented workaround is to turn off Wi-Fi on the phone, turn on the phone’s hotspot, and connect the Windows PC to that hotspot. This creates a local link between the two devices; it is not a cloud upload.

A hotspot can still involve your carrier’s cellular connection. Mobile-carrier hotspot charges or data allowances are separate from internet access, so check your plan if the hotspot keeps cellular data active. If you must avoid cellular data entirely, return to USB instead of assuming a hotspot is cost-free.

Quick Share troubleshooting

• The PC cannot see the phone: turn on Bluetooth on both devices, confirm Wi-Fi or Ethernet is enabled, put both on the same network, and check Quick Share visibility settings.
• The phone sees the PC but sending fails: move the devices closer, approve the request promptly, and check whether the network uses client isolation. Try the phone-hotspot workaround if it does.
• No Windows app is available: verify whether the PC is non-Samsung or Samsung and install the corresponding app. Confirm the Windows edition and architecture meet Google’s listed requirements.
• The request never appears: recheck visibility on the receiving device, leave Quick Share open, and confirm that Bluetooth remains enabled.
• You are in a restricted location: Google lists availability exceptions for Cuba, Iran, North Korea and Syria. Availability can change, so check Google’s current local guidance before relying on Quick Share.

Method 3: Transfer with Microsoft Phone Link

Phone Link and Android’s Link to Windows can share files, but they are not the first choice for a transfer that must be independent of internet access. Microsoft’s current requirements call for Windows 10 with the October 2022 update or later, or Windows 11; Android 10 or later; the phone and PC on the same Wi-Fi network; Link to Windows; and a Microsoft account for pairing.

This makes Phone Link most practical for someone who has already paired the devices and regularly uses the app. If you are starting from scratch on an offline PC, account sign-in, app installation and pairing can be more work than plugging in a cable.

Version requirements for file sharing

For Microsoft’s documented share-files flow, Link to Windows on Android must be version 1.24032.518.0 or later, and Phone Link on Windows must be version 1.24032.156.0 or later. Check the installed versions before troubleshooting a missing share option. A general Phone Link installation does not automatically mean every newer file-sharing workflow is available.

Copy-and-paste and mobile-data behavior

Microsoft says cross-device copy and paste can use mobile data when syncing over mobile data is allowed and Wi-Fi is unavailable. If avoiding cellular charges or any off-network transfer is part of your requirement, inspect Phone Link’s setting for syncing over mobile data and disable it before copying. This setting matters even when your intention is only to move text or files locally.

Drag-and-drop limits

Microsoft’s documented Phone Link drag-and-drop feature has narrower conditions than Phone Link as a whole:

• It requires a supported Samsung device and the phone and PC on the same Wi-Fi network.
• It supports files, not folders.
• It allows up to 100 files at a time.
• Each file can be up to 512 MB.

Those limits apply to the documented drag-and-drop feature; do not assume they apply to every Phone Link sharing workflow. If you need to move a folder tree or files larger than 512 MB, USB or another supported workflow is a safer plan.

Why Phone Link may not be fully offline

Pairing, account sign-in, app updates and some synchronization behavior can involve services beyond the local Wi-Fi connection. Phone Link may continue to work for an already-paired local session, but Microsoft’s requirements do not establish that every workflow is internet-free. Use USB when “no internet and no cellular data” is a hard requirement.

Also note that Microsoft ended Windows 10 support on October 14, 2025. A Windows 10 PC may still run these transfer features, but Microsoft no longer provides free Windows Update software updates, technical assistance or security fixes for that operating system. That support status does not itself prevent a transfer, but it is relevant when deciding whether the computer should remain in regular service.

Which method should you use?

Use USB when

• You have no usable Wi-Fi network or hotspot.
• You must avoid both internet and cellular data.
• You want the least setup and the clearest folder-level access.
• You are moving a large collection and do not want wireless discovery or approval steps.
• You are unsure whether the Windows and Android sharing apps meet their version requirements.

Use Quick Share when

• The devices are nearby and you want to avoid a cable.
• Both devices can join the same local network, or the phone can provide a hotspot.
• You are sending selected photos, videos, documents or folders rather than managing the phone’s entire storage.
• You want encrypted sharing with an approval prompt for incoming files.
• The PC meets Google’s 64-bit Windows requirement and the phone runs Android 6.0 or later.

Use Phone Link when

• Phone Link and Link to Windows are already paired and current.
• You want file sharing alongside Phone Link’s other PC/phone features.
• You can meet the same-Wi-Fi, account and device-compatibility requirements.
• The specific file workflow fits its limits, especially the Samsung-only drag-and-drop path.
• You have checked whether cross-device syncing is permitted to use mobile data.

Practical checks before and after a transfer

1. Check the connection: for USB, confirm the cable supports data; for wireless, confirm Bluetooth and the required local network are active.
2. Check the phone state: unlock it and select the correct USB mode or approve the wireless request.
3. Check destination space: ensure the computer or phone has enough free storage for the files.
4. Keep the devices awake: screen locks, visibility changes and network roaming can interrupt a transfer.
5. Transfer a small test batch: copy one or two representative files first if you are using an unfamiliar cable, app or network.
6. Verify the result: open representative files at the destination and compare counts or folder contents before deleting originals.
7. Disconnect safely: eject a USB device in Windows before unplugging it; close wireless transfer windows only after completion is reported.

Common questions

Can I transfer files with a USB cable if the PC has no internet?

Yes. USB file transfer is a direct phone-to-PC connection. Internet access is not part of the procedure.

Why does my Android phone charge but not appear in Windows?

The cable may be charge-only, or the phone may still be set to charging mode. Use a data-capable cable, unlock the phone, open Charging this device via USB, and choose File transfer.

Can I use USB without Wi-Fi or Bluetooth?

Yes. USB does not require either wireless radio or a local network. It only requires a compatible, data-capable cable and the correct USB mode on the phone.

Does Quick Share require internet?

Google’s instructions require Bluetooth, Wi-Fi or Ethernet, and the same network, but they do not describe a cloud upload requirement. A local router network or a direct phone-hotspot setup can provide the needed connection without internet service.

Will a phone hotspot always be free?

No. The hotspot is a local connection, but it may keep cellular data active. Check your carrier’s hotspot allowance and charges. If cellular data is prohibited, use USB.

Where does Quick Share save files on Windows?

Google documents the destination as the Quick Share folder inside Downloads.

Do both Quick Share devices need to be close?

Google’s Quick Share for Windows product page lists about 5 metres (16 feet). Keep the devices nearby and account for walls or other interference.

Can Quick Share send folders?

The Windows Quick Share workflow supports selecting or dragging files and folders. The receiving phone or PC still needs enough storage, and the transfer must be accepted on the receiving device unless the same Google Account allows automatic acceptance.

Can Phone Link transfer folders?

Not through Microsoft’s documented drag-and-drop feature: that workflow supports files, not folders, and is limited to 100 files at a time and 512 MB per file.

Does every Phone Link workflow avoid the internet?

No guarantee is given. Phone Link requires same-Wi-Fi pairing and a Microsoft account, and cross-device copy and paste can use mobile data when that option is enabled. Choose USB for a strict no-internet, no-cellular-data requirement.

Is Windows 10 still supported for these transfers?

Windows 10 may still run the features, but Microsoft ended support on October 14, 2025. It no longer provides free Windows Update software updates, technical assistance or security fixes for Windows 10.

What are Phone Link’s drag-and-drop limits?

Microsoft’s documented drag-and-drop feature supports files, not folders, up to 100 files at a time and 512 MB per file, and requires a supported Samsung phone on the same Wi-Fi.

Could Phone Link use cellular data?

Cross-device copy and paste can use mobile data when syncing over mobile data is allowed and Wi-Fi is unavailable. Disable that option if cellular usage is not acceptable.

Which app should a Samsung Windows PC use for Quick Share?

Samsung PCs should use Samsung’s Quick Share app from the Microsoft Store; non-Samsung Windows PCs use Google’s Quick Share app.

What Android version does Quick Share support?

Google lists Android 6.0 and later. Google lists 64-bit Windows 10 or later, with ARM-based PCs requiring Windows 11 or later.

The Bottom Line

For a dependable transfer with no internet connection, use USB: choose a data-capable cable, select File transfer on the unlocked Android phone, copy in Windows, verify the files and eject safely. For cable-free sharing, Quick Share works over Bluetooth plus a shared local network or phone hotspot. Phone Link is best reserved for devices that are already paired and meet its account, Wi-Fi, version and feature-specific requirements.
