How to transfer files from your computer to your laptop via Wi-Fi: all the working methods

Transfer files between computers via Wi-Fi network — one of the most convenient ways to exchange data without wires or flash drives. This is especially relevant for large files (videos, archives, disk images) when USB drives are too slow or simply unavailable. But how do you properly organize the transfer to ensure it's fast, stable, and secure?

In this article we will look at 7 proven methods — from creating a local network to using cloud services and specialized programs. You'll learn which method is suitable for transferring 100 MB text documents, and which one can handle it 50 GB video materials. We'll also compare the transfer speed, setup complexity, and security level of each option so you can choose the best one.

Important: If you work with sensitive data (such as financial statements or personal photographs), please refer to the sections about encryption And secure protocolsNot all methods are equally safe!

1. Transfer via local network (SMB/FTP)

The most classic and universal method is to use SMB protocols (for Windows) or FTP (cross-platform). It doesn't require any third-party software, but it does require minimal network configuration. The transfer speed depends on the standard of your Wi-Fi router: Wi-Fi 5 (802.11ac) you can get up to 50-70 MB/s, and on Wi-Fi 6 (802.11ax) — to 100+ MB/s.

How does it work? One computer acts as servers (opens access to the folder), and the second one - client (connects and downloads files). The advantage of this method: there are no file size limits, you can transfer entire folders with their structure, and also use direct connection without a router (via Wi-Fi Direct or hotspot).

• ✅ Doesn't require internet connection - works in an isolated network
• ✅ Supports download resumption after interruption
• ✅ You can configure access rights (read/write only)
• ⚠️ Requires firewall configuration (may block the connection)

Detailed instructions for Windows:

1. On main PC open Control Panel → Network Settings → Advanced Sharing Settings.
2. Turn on Network discovery And File and Printer Sharing for profile "Private".
3. Right click on the folder you want to share, select Properties → Access → Share.
4. On laptop open File Explorer → Network and find the name of the primary PC. The folder will be available for copying.

-->

⚠️ Attention: In Windows 10/11, the legacy protocol is disabled by default. SMBv1 (unsafe!) If your laptop doesn't see the folder, turn it on SMBv2/v3 through Control Panel → Programs → Turn on Windows features.

2. Using an FTP server (FileZilla, WS_FTP)

If you need to transfer files regularly or work with large amounts of data (for example, backups, video for editing), setting up FTP servers will be the optimal solution. Unlike SMB, FTP works on all platforms (Windows, macOS, Linux) and allows for flexible access control.

To set up an FTP connection you will need a server program (for example, FileZilla Server) and the client (for example, WinSCP or the same FileZilla Client). The transfer speed is limited only by the capabilities of your Wi-Fi network. The main advantage is that you can customize encryption (through FTPS or SFTP), which is important for confidential data.

Step-by-step instructions for FileZilla Server:

1. Download and install FileZilla Server on the main PC.
2. Specify the port on first launch 21 (standard for FTP) and create a user with a password.
3. In the user settings, specify the folder that the user will have access to.
4. On your laptop, connect via FileZilla Client, entering the IP address of the main PC (you can find it out using the command ipconfig V CMD).

3. Direct transfer programs (LocalSend, Snapdrop)

If you need to transfer files one-time and without unnecessary settings, use specialized utilities for direct exchange via Wi-FiThey operate on a point-to-point basis and do not require an internet connection. Popular solutions:

• 📱 LocalSend — open source, cross-platform (Windows, macOS, Linux, Android), encryption AES-256.
• 🌐 Snapdrop — web version (works through a browser), does not require installation, but the speed is limited.
• 💻 Feem - supports folder transfer, there is a chat for exchanging messages.

LocalSend is the only program on this list that doesn't send file metadata to external servers (unlike Snapdrop, which uses WebRTC through an intermediary server). This makes it ideal for conveying sensitive information.

How to use LocalSend:

1. Install the program on both devices (official website).
2. Make sure both PCs are connected to the same Wi-Fi network.
3. On the main computer, select the files and click Send, then select your laptop from the list of devices.
4. On your laptop, confirm receipt of files.

⚠️ Attention: Programs like Snapdrop And Feem may conflict with corporate networks where it is blocked multicastIn this case, use LocalSend or FTP.

4. Cloud services (Google Drive, Dropbox, Yandex Disk)

If the transfer speed is not critical and the files do not exceed 10-15 GB, the easiest way is to use cloud storageThis method is convenient because it doesn't require network configuration—just upload files to the server and then download them to your laptop. However, there are some limitations:

• 📉 The speed depends on your internet channel (upload/download).
• 🔒 Free plans have limits (for example, Google Drive gives 15 GB, Yandex Disk — 10 GB).
• ⏳ Large files (>5GB) may take time to load.

Comparison of popular services:

How to transfer files via Yandex Disk:

1. Upload files to the folder Yandex Disk on the main PC (via Explorer or web interface).
2. Generate public link on a folder or file (right click → Share).
3. Open the link on your laptop and download the files.

How to speed up cloud uploads?

Use a desktop app instead of a browser—it supports multi-threaded downloads. Also, disable other bandwidth-hungry programs (torrents, online games) and connect to the router via cable (if possible).

5. Transfer via SSH (for Linux/macOS)

If you work in an ecosystem Linux or macOS, the most reliable way to transfer files is to use the protocol SSH (Secure Shell). It provides full encryption data and doesn't require additional software (everything you need is already built into the system). Speed ​​is limited only by your network bandwidth.

The command used for transmission is scp (Secure Copy) or rsync (for folder synchronization). The main advantage is safety: Even if someone intercepts the traffic, it will be impossible to decrypt it without the key.

An example command for copying a file from a PC to a laptop:

scp /path/to/file user@laptop_ip_address:/destination/path

Where:

• user — account name on the laptop;
• laptop IP address — local IP (you can find out using the command ifconfig on macOS/Linux or ipconfig on Windows);
• /path/destination — the folder where the file will be copied.

⚠️ Attention: To connect via SSH, the SSH server must be running on your laptop. On macOS, it is enabled in System Preferences → Sharing → Remote Login. On Linux install the package openssh-server.

6. Wi-Fi Direct and Hotspot (without a router)

If you don't have a router or you're in a place without Wi-Fi (like on a train), you can organize direct connection between computers. There are two options for this:

1. Wi-Fi Direct — a technology that allows devices to connect without an intermediary (like Bluetooth, but faster). Supported by most modern laptops.
2. Hotspot mode - one of the computers distributes Wi-Fi, and the second one connects to it.

The speed in such a connection is lower than through a router (usually 10-30 MB/s), but this is enough for transferring documents or photos. The main advantage is no additional equipment required.

How to set up a Hotspot on Windows:

1. Open Settings → Network & Internet → Mobile Hotspot.
2. In the field Sharing select internet connection (if available) or leave No internet access.
3. Set the network name and password, then turn it on Mobile hotspot.
4. Connect your laptop to the created network and use any transfer method (SMB, FTP, LocalSend).

7. Specialized utilities (Resilio Sync, Syncthing)

For folder synchronization programs like Resilio Sync or SyncthingThey work on the principle peer-to-peer (without a central server) and use Wi-Fi or the internet to transfer changes. This is convenient if you regularly update files (for example, if you're working on a project from a laptop and a PC).

Peculiarities Syncthing:

• 🔄 Syncing works both ways (changes on any device apply to all others).
• 🔒 Encryption TLS to protect data.
• 📂 You can exclude specific files or folders from syncing.

How to set up Syncthing:

1. Install the program on both computers (syncthing.net).
2. On the main PC, add a folder for synchronization and generate Device ID.
3. On the laptop, enter the ID of the main PC and confirm the connection.
4. Select a folder to sync on your laptop—data will start copying automatically.

⚠️ Attention: When you sync a large folder for the first time (for example, 100+ GB) use a cable Ethernet Or connect both devices to the router via a wire. This will speed up the process 5-10 times.

FAQ: Frequently Asked Questions

Is it possible to transfer files between Windows and macOS?

Yes, but it is better to use cross-platform methods:

• FTP (FileZilla);
• SSH (if enabled on macOS Remote login);
• LocalSend or Snapdrop;
• Cloud services (Google Drive, Dropbox).

SMB also works, but may require additional settings on macOS (enabling SMB support in System Preferences → Sharing).

Why is Wi-Fi transmission speed lower than cable?

Wi-Fi always loses out to a wired connection in terms of speed and stability. The main reasons are:

• Interference from other networks or household appliances (microwaves, cordless phones);
• Limitations of the standard: even Wi-Fi 6 (802.11ax) rarely exceeds the speed in real-world conditions 100 MB/s, while Gigabit Ethernet provides 125 MB/s;
• CPU load: Wi-Fi traffic encryption (WPA3) requires resources;
• Distance to the router: the further, the lower the speed.

If you need maximum speed, connect one computer to the router via cable, and leave the other on Wi-Fi. This will transfer data over the local network, but without doubling the load on the wireless channel.

How to transfer files larger than 100 GB?

For large amounts of data (100+ GB) we recommend:

1. Use FTP with optimization:
   • Set up passive mode in FileZilla Server;
   • Disable your antivirus during the transfer;
   • Connect both PCs to the router via cable (if possible).

Split a file into parts using an archiver (7-Zip, WinRAR) and transfer in parts.

Use an external hard drive (if the network speed is critically low).

Cloud services are not suitable for such volumes due to file size limitations and low download speeds.

Is it possible to transfer files via Wi-Fi between computers on different networks?

Yes, but this will require:

1. Cloud service (Google Drive, Dropbox) - simple but slow method;
2. VPN server:
   • Set up a VPN on one of the PCs (for example, via WireGuard or OpenVPN);
   • Connect a second computer to this VPN;
   • Use SMB/FTP to transfer files.

Port forwarding on a router (for FTP or SSH), but it is not secure if you have white IP.

For a one-time transfer, it's easier to use the cloud. For regular sharing, set up a VPN.

How to protect transferred files from interception?

If you work with sensitive data, follow these guidelines:

• Use encryption:
  • For FTP - configure FTPS or SFTP;
  • For SMB - enable SMB 3.0+ with encryption;
  • For SSH, use keys instead of passwords.
• Avoid public networks (cafes, airports) for transferring important files;
• Archive files with a password before transfer (7-Zip supports AES-256);
• Turn off network discovery after transfer (in Windows settings).

If you are transmitting data over an open network (for example, in a hotel), use VPN to create a secure tunnel.
