Why We Built TreeTalk Node
This frustration hit home in our own workflow. Small development team, mixed Windows environment (some machines running Windows 7 for legacy testing, others on Windows 11), frequent need to move builds, logs, design files, and documentation between systems.
- SMB/network shares require IT configuration most users can’t do themselves, and discovery is terrible (“Is Bob’s machine \DESKTOP-X7K2 or \BOB-PC?”)
- FTP/file servers need dedicated infrastructure and someone to maintain it
- P2P sync tools (Syncthing, Resilio) are built for continuous folder synchronization, not quick interactive transfers
- Legacy LAN messengers have outdated UIs, poor file handling, and security practices from 2005
How It Actually Works
TreeTalk Node treats your local network the way it should be treated: as a fast, private space you already control.
• Direct PC-to-PC transfers use the full capacity of your local network — typically 100 Mbps to 10 Gbps depending on infrastructure. A 2GB video file that would take 15 minutes via cloud upload/download moves in under 30 seconds on a gigabit LAN.
• Integrated team chat sits alongside the peer list. Quick coordination (“Sending updated specs now”) without switching apps. Group chat for project team, private messages for one-on-one communication.
• File journal logs every sent and received file with timestamp, sender/receiver, and quick access buttons. Opens the file or containing folder instantly. Critical for compliance, auditing, and just remembering “where did that report go?”
• Optional end-to-end encryption for environments where regulatory requirements or shared infrastructure demand it. For small offices where simplicity matters more, unencrypted mode removes complexity (and works faster).
• Zero infrastructure requirements — no dedicated servers, no NAS, no cloud subscriptions. Works on existing network hardware you already have.
• Portable executable means no installation, no admin rights needed, no IT deployment headaches. Copy the .exe to a USB drive, distribute via email, or drop it in a shared folder. Users just double-click and they’re connected.
• Windows 7 SP1 through Windows 11 support matters more than you’d think. Manufacturing plants, logistics hubs, point-of-sale terminals, warehouse management systems — the real world runs on mixed fleets where “just upgrade everything” isn’t an option. Watch how it works in practice: Demo Video
Who This Actually Solves Problems For
Creative & Development Teams
Workstations exchanging large design assets, source builds, project archives, media exports, and test datasets. Mixed environments (Windows/macOS/Linux), shared WiFi and wired LAN, VPN links between offices or remote teammates, and workflows that can’t wait for cloud sync or upload limits. TreeTalk Node fits the real pipeline: fast peer-to-peer transfers, no cloud dependency, works across VLANs with proper routing (or over VPN as a LAN), and runs on everyday hardware without changing how your team works.Manufacturing & Industrial Operations
Shop floor computers exchanging production schedules, quality control reports, machine configurations. Often older Windows installations, segmented networks for security, unreliable or non-existent Internet connectivity. TreeTalk Node handles the messy reality: no cloud dependency, works across VLANs with proper routing, runs on decade-old hardware.Logistics & Transportation
Dispatch centers sending route manifests and delivery updates to driver terminals. Warehouse systems exchanging inventory reports. Field offices with temporary network setups. Fast transfers of time-sensitive documents without relying on external connectivity.
Healthcare & Regulated Environments
Medical offices, labs, clinics where HIPAA compliance makes cloud tools risky and expensive. Patient data, imaging files, lab results staying strictly within the local network perimeter. Optional encryption plus audit logs for regulatory documentation.Education & Training
Computer labs where teachers need to distribute assignments to 30 student machines simultaneously, or collect completed work back. No student accounts to provision, no cloud storage quotas to manage, no Internet bandwidth bottlenecks during class.
The Data Sovereignty Advantage
Here’s what doesn’t happen with TreeTalk Node:- Your files don’t pass through third-party servers
- No company in another jurisdiction can access your data
- No metadata harvesting for analytics or advertising
- No surprise terms-of-service changes affecting your workflow
- No “we’re shutting down this feature” announcements
What Happens Next
We’re refining TreeTalk Node based on real-world usage in our beta program. We’re especially interested in feedback from:- IT managers deploying in mixed or restricted environments
- Operations teams in manufacturing, logistics, or field services
- Compliance officers evaluating data residency solutions
- Anyone tired of using cloud tools for purely local file transfers
- What makes file sharing convenient for your specific workflow?
- What slows you down most with current tools?
- Which features matter most in your environment?
Frequently Asked Questions
1 How to Share Large Files on a Local Network (LAN) or Wi-Fi Network
For transferring large files from hundreds of megabytes to multiple gigabytes (like CAD files, Full HD videos, BlueRay movies or 4K Ultra High Definition content), TreeTalk Node provides the most convenient solution.
Just drag and drop files onto a recipient’s nickname or group chat, or click the “Send File” button. Files transfer directly between computers without touching the internet, making it much faster and more secure than cloud storage — ideal for critical infrastructure and air-gapped networks.
2 How to Transfer Large Files Over the Internet
For transferring large files (hundreds of megabytes to several gigabytes) over the internet, combine TreeTalk Node with a VPN service.
VPN solutions like OpenVPN or SoftEther create secure encrypted connections between devices. TreeTalk Node recognizes this VPN tunnel as a local network and automatically discovers other devices as if they were on the same LAN.
Simply drag and drop files to the recipient or use the “Send File” button. Files are delivered peer-to-peer without cloud services or online storage, ensuring faster speeds and better security.
3 Do I need the Internet or a server to use TreeTalk Node?
No. TreeTalk Node operates entirely within your local network.
Internet access, cloud accounts, and central servers are not required.
Everything—file transfers and messages—remains within your LAN, WiFi, WiFi Halow, or VPN environment, delivering superior privacy, speed, and reliability even in offline or isolated network scenarios.
4 Will TreeTalk Node work on older Windows systems like Windows 7?
Yes. TreeTalk Node is compatible with Windows 7 SP1 through Windows 11.
It’s specifically designed for mixed-age environments where legacy and modern systems work side-by-side—perfect for offices, manufacturing facilities, educational institutions, and home networks with varied hardware configurations.
5 Is TreeTalk Node safe to use for sensitive files?
Yes, completely safe.
TreeTalk Node confines all transfers to your internal network and provides optional end-to-end encryption when extra security is needed.
Your files never leave your network perimeter, no external servers are involved, and you maintain complete control over your data at all times.
6 Do I need to install anything or configure networks?
No installation or configuration necessary.
TreeTalk Node runs as a portable executable:
- Download it to your devices,
- Double-click to launch,
- Watch it automatically find peers on your network.
No driver installation, no firewall modifications, no IT deployment complexity—it simply works out of the box.
7 How fast is file transfer in TreeTalk Node?
Transfers leverage the full bandwidth of your LAN, WiFi, or VPN connection, eliminating the bottlenecks created by cloud services and protocol overhead.
Files move peer-to-peer between computers at native network speeds—consistently outperforming email attachments, messaging apps, SMB shares, and USB drives, particularly when moving large files.
TreeTalk builds communication infrastructure for environments where privacy, security, and independence matter. TreeTalk Node is our answer to the question: “Why is sending a file across the room harder than sending it around the world?”
