Most people associate torrenting with downloading movies or software from the internet. But the BitTorrent protocol is equally powerful as a local file transfer tool — and for large files, it is often faster, more reliable, and more flexible than traditional methods like USB drives, email attachments, or cloud uploads.
Whether you are moving a large video project between two computers on the same network, sharing a folder of files with a colleague across the city, or transferring a backup archive between two machines without a cloud service in the middle, BitTorrent handles it cleanly.
This guide walks you through the complete process of sharing files from one PC to another using a torrent — from creating the torrent file to completing the transfer on the receiving end.
Why Use Torrent for File Transfer Between PCs?
Before getting into the steps, here is why this method is worth knowing.
Advantages Over Other Transfer Methods
- No file size limits — unlike email attachments (25MB cap) or some cloud services, torrents handle files of any size
- No cloud dependency — files transfer directly between machines without touching a third-party server
- Built-in integrity verification — BitTorrent verifies every piece of the file using SHA-1 hashing. If any data is corrupted during transfer, it is automatically re-downloaded
- Pause and resume — the transfer can be paused and resumed at any point without starting over
- Multiple files at once — you can package an entire folder structure into a single torrent and transfer it as one unit
- Works over LAN and internet — the same method works whether both PCs are on the same local network or on opposite sides of the world
What You Need Before You Start
Make sure the following are ready on both computers before beginning:
- A torrent client installed on both PCs — qBittorrent is recommended (free, open source, no bundled software)
- The files you want to transfer ready on the sending PC
- Both PCs connected to the internet or the same local network
- If transferring over the internet — the sender’s IP address and an open port on their router
Step 1 — Install qBittorrent on Both PCs
qBittorrent is the best free torrent client for this purpose. It is lightweight, ad-free, and available for Windows, macOS, and Linux.
How to Install qBittorrent
- Go to qbittorrent-tracker.net — the official qBittorrent website
- Download the installer for your operating system
- Run the installer and follow the on-screen prompts
- Launch qBittorrent after installation
Repeat this on both the sending PC and the receiving PC.
Step 2 — Create the Torrent File on the Sending PC
The sending PC needs to package the files into a torrent. This is done directly inside qBittorrent.
Opening the Torrent Creator
- Open qBittorrent on the sending PC
- Go to the top menu bar and click Tools
- Click Torrent Creator from the dropdown menu
The Create Torrent window will open.
Selecting the Files or Folder
- Click the File button to select a single file, or click the Folder button to select an entire folder
- Navigate to the files you want to share and select them
- The selected path will appear in the input field at the top of the window
Setting the Piece Size
- Leave the Piece Size setting on Auto — qBittorrent will calculate the best piece size based on your total file size
- For very large files (above 10GB), you can manually set a larger piece size (2MB or 4MB) for slightly better efficiency
Tracker Settings — Two Options
This is the most important decision in the setup. You have two options depending on your situation:
Option A — Using a Public Tracker (Easiest for Internet Transfers)
A public tracker helps the two computers find each other over the internet.
- In the Tracker URLs field, paste one or more public tracker URLs
- Reliable public trackers include:
- udp://tracker.opentrackr.org:1337/announce
- udp://open.tracker.cl:1337/announce
- udp://tracker.openbittorrent.com:80/announce
- Add each tracker URL on a separate line
Option B — No Tracker (For Local Network Transfers)
If both PCs are on the same local network (same WiFi router or LAN), you do not need a tracker at all. The two clients can find each other directly using their local IP addresses.
- Leave the Tracker URLs field empty
- Enable DHT and Peer Exchange in qBittorrent settings for better local peer discovery
Private Torrent Option
If you want to prevent anyone else from downloading this torrent if the .torrent file is shared, check the Private Torrent box. This disables DHT and PEX for this specific torrent — only people with the torrent file and tracker access can download it.
For a private two-person file transfer, enabling this option is a good practice.
Creating the Torrent
- Once the settings are configured, click Create Torrent
- A save dialog will appear — choose where to save the .torrent file on your PC
- Name the .torrent file clearly and click Save
qBittorrent will hash all the files and generate the .torrent file. For large files this may take a few minutes.
Step 3 — Start Seeding on the Sending PC
After creating the torrent, you need to start seeding it — this means making the files available for download.
Adding the Torrent to qBittorrent for Seeding
- qBittorrent may automatically ask if you want to add the newly created torrent — click Yes or OK if it does
- If it does not prompt automatically:
- Go to File in the qBittorrent menu
- Click Add Torrent File
- Navigate to the .torrent file you just created and open it
Setting the Save Path
- A dialog box will appear asking where the files are located
- Set the Save Path to the folder containing the actual files you are sharing
- This tells qBittorrent where the source files are so it can begin seeding them immediately
Starting the Seed
- Click OK to confirm
- The torrent will appear in qBittorrent’s list with the status Seeding
- The sending PC is now ready to upload the files to whoever connects
Step 4 — Send the .torrent File to the Receiving PC
The receiving PC needs the .torrent file to begin downloading. Send it using any method available:
- Email it as an attachment
- Share it via WhatsApp, Telegram, or any messaging app
- Upload it to Google Drive or Dropbox and share the link
- Transfer it via USB drive if both machines are nearby
- Share it directly over your local network using Windows File Sharing or a shared folder
The .torrent file is tiny — typically under 100KB — so it transfers instantly via any method.
Step 5 — Configure Port Forwarding (For Internet Transfers Only)
If both PCs are on the same local network, skip this step entirely.
For transfers over the internet, the sending PC needs an open port so the receiving PC can connect to it directly.
Why Port Forwarding Is Needed
Home routers use NAT (Network Address Translation) to share a single public IP address across multiple devices. Incoming connections from the internet are blocked by default unless you explicitly tell the router which device they should go to.
How to Set Up Port Forwarding
- Open qBittorrent on the sending PC
- Go to Tools, then Options (or Preferences on macOS)
- Click the Connection tab
- Note the port number shown under Incoming Connections — for example 6881
- Log in to your router’s admin panel — typically accessed at 192.168.0.1 or 192.168.1.1 in your browser
- Find the Port Forwarding section — this is usually under Advanced, NAT, or Firewall settings
- Create a new port forwarding rule:
- External port: the qBittorrent port number (e.g. 6881)
- Internal IP: the local IP address of the sending PC (find this by running ipconfig in Command Prompt on Windows)
- Internal port: same as external port
- Protocol: TCP and UDP
- Save the rule
Finding Your Public IP Address
The receiving PC also needs to know the sender’s public IP address to connect directly if the tracker is not being used.
- On the sending PC, visit whatismyip.com
- Note the IPv4 address shown — this is the public address the receiving PC will use to connect
Step 6 — Download the Files on the Receiving PC
Now the receiving PC can begin downloading.
Adding the Torrent to qBittorrent
- Open qBittorrent on the receiving PC
- Go to File and click Add Torrent File
- Navigate to the .torrent file that was sent and open it
- A dialog box will appear showing the file list and total size
Setting the Download Location
- In the Save Path field, choose where you want the downloaded files to be saved
- Click OK to begin
Connecting to the Sender
qBittorrent will immediately attempt to connect to the sending PC using:
- The tracker URLs specified in the torrent (if any)
- DHT peer discovery
- Direct connection to the sender’s IP if both are on the same local network
If both PCs are on the same local network, the connection typically establishes within seconds. Over the internet with a tracker, connection usually happens within 30 to 60 seconds.
Step 7 — Monitor the Transfer
Both PCs can monitor the transfer in real time inside qBittorrent.
On the Sending PC
- The torrent shows status as Seeding
- The Upload Speed column shows how fast data is being sent
- The Uploaded column shows the total amount transferred so far
On the Receiving PC
- The torrent shows status as Downloading
- The Download Speed column shows transfer speed
- The Progress bar fills as pieces are verified and written to disk
- The ETA column shows estimated time to completion
Expected Transfer Speeds
- Same local network (LAN cable): up to 1000 Mbps depending on router and network adapter speed
- Same local network (WiFi): typically 50 to 300 Mbps depending on WiFi standard and signal strength
- Over the internet: limited by the upload speed of the sending PC’s internet connection
Step 8 — Verify the Transfer Is Complete
When the download reaches 100%, qBittorrent automatically verifies all pieces against the hashes in the torrent file. If every piece passes verification, the status changes from Downloading to Seeding on the receiving PC as well.
You can optionally force a manual re-check:
- Right-click the completed torrent in qBittorrent
- Click Force Recheck
- qBittorrent will scan every piece and confirm the integrity of the downloaded files
If any piece fails verification, qBittorrent automatically re-downloads it from the sending PC. This makes BitTorrent one of the most reliable file transfer methods available — data corruption is automatically detected and corrected.
Troubleshooting Common Issues
The Download Is Not Starting
- Confirm the sending PC’s torrent status shows Seeding and not Paused or Stopped
- Check that the .torrent file on the receiving PC matches the one created on the sending PC
- If using a tracker, verify the tracker URLs are correct and the tracker is reachable
- If transferring over the internet, confirm port forwarding is configured correctly on the sender’s router
Transfer Speed Is Very Slow
- Check the sender’s upload speed limit — qBittorrent has a global upload rate limit that may be set too low. Go to Tools, Options, Speed, and set the upload limit higher or to unlimited
- On local network transfers, check if both PCs are connected via WiFi rather than LAN cable — a wired connection is significantly faster
- Confirm no other applications are consuming the available bandwidth on either PC
Both PCs Are on the Same Network but Not Connecting
- Make sure qBittorrent is allowed through the Windows Firewall on both PCs
- Go to Windows Security, Firewall and Network Protection, Allow an App Through Firewall, and confirm qBittorrent is listed and checked
- Try disabling the Windows Firewall temporarily on both PCs to confirm it is the source of the problem, then re-enable and add the exception properly
The Torrent Shows Error — Tracker Not Working
- If the tracker URL is unreachable, the torrent may show a tracker error
- This does not prevent local network transfers — qBittorrent will still find the sending PC through DHT and local peer discovery
- Add additional tracker URLs by right-clicking the torrent, clicking Edit Trackers, and adding backup tracker addresses
Alternative — Using a Magnet Link Instead of a .torrent File
Instead of sending a .torrent file, you can generate a magnet link from the torrent and share that instead.
How to Get the Magnet Link
- On the sending PC, right-click the seeding torrent in qBittorrent
- Click Copy Magnet Link
- Paste and send this link to the receiving PC via any messaging method
Using the Magnet Link on the Receiving PC
- Copy the magnet link
- Open qBittorrent on the receiving PC
- Go to File and click Add Torrent from URL
- Paste the magnet link and click Download
- qBittorrent will fetch the metadata from the sending PC and begin downloading
The magnet link approach eliminates the step of sending a separate .torrent file — useful when you want to start the transfer immediately without saving an intermediate file.
Quick Summary — The Complete Process
- Install qBittorrent on both PCs
- Create a torrent from the files on the sending PC using Tools and Torrent Creator
- Add tracker URLs if transferring over the internet
- Start seeding on the sending PC
- Send the .torrent file or magnet link to the receiving PC
- Set up port forwarding on the sender’s router if transferring over the internet
- Open the .torrent file or magnet link on the receiving PC
- Monitor the transfer until complete
- Verify the completed files on the receiving PC
Final Thoughts
Using BitTorrent to share files between two PCs is a practical, reliable method that works equally well on a local network and across the internet. The built-in hash verification means you can be confident the transferred files are bit-for-bit identical to the originals — something that many other transfer methods cannot guarantee.
For large files, folder transfers, or situations where cloud services are not an option, this method is one of the cleanest solutions available. Once you have done it once, the process becomes second nature.
FAQ
Q: Can I use torrent to share files on a local network without internet?
A: Yes. If both PCs are on the same local network, qBittorrent can find the sending PC through DHT and local peer discovery without any tracker or internet connection. Simply create the torrent without adding tracker URLs and transfer the .torrent file or magnet link between the two machines via USB or local network share.
Q: What is the fastest way to transfer large files using torrent?
A: For the fastest transfer, connect both PCs to the same router via ethernet LAN cable rather than WiFi. A wired gigabit connection can transfer files at up to 1000 Mbps — significantly faster than WiFi. Remove any upload and download speed limits in qBittorrent settings under Tools, Options, and Speed.
Q: Do I need to keep the sending PC on until the transfer is complete?
A: Yes. The sending PC must remain on, connected, and actively seeding for the receiving PC to download the files. If the sending PC goes to sleep or shuts down, the download will pause until the connection is restored.
Q: Is it safe to share files between two PCs using torrent?
A: Yes, for files you created yourself. The torrent you create from your own files carries no malware risk. The BitTorrent protocol itself is safe — the only risk in normal torrenting comes from downloading content from unknown sources, which does not apply when you are the one creating and seeding the torrent.
Q: Can I transfer multiple folders at once using a torrent?
A: Yes. When creating the torrent in qBittorrent using the Folder option, you can select an entire folder containing multiple subfolders and files. The entire directory structure is preserved in the torrent and recreated exactly on the receiving PC after the download completes.
Q: How does BitTorrent verify that files transferred correctly?
A: BitTorrent divides files into pieces and computes a SHA-1 cryptographic hash for each piece during torrent creation. As the receiving PC downloads each piece, it computes the hash again and compares it against the value stored in the torrent file. If the hashes match, the piece is written to disk. If they do not match, the piece is discarded and re-downloaded. This process guarantees the transferred files are bit-for-bit identical to the originals.
