# Advanced file transfer: what it means and how to do it for free

> Advanced file transfer means going beyond the email attachment: sending files of any size and whole folders, to several recipients, by link or QR code, without accounts or stored copies. A free browser tool such as StrongFolder covers these person-to-person needs with direct peer-to-peer transfer. Automated, audited system-to-system transfers need a managed file transfer (MFT) platform.

1. **Open StrongFolder** — Go to [strongfolder.com](https://strongfolder.com) or click the StrongFolder Chrome extension. No account is needed.
2. **Add large files or whole folders** — Pick any number of files or a folder with subfolders. Nothing is uploaded or zipped.
3. **Share one link with everyone** — Copy the link for chat or e-mail, or show the QR code to a phone. Several recipients can open the same link.
4. **Keep sharing, then stop** — Keep the tab open while recipients download. Click Stop Sharing when everyone has the files — the link then stops working.

"Advanced file transfer" is a phrase people search when the basic tools stop working: the
attachment bounces, the transfer service wants a paid plan, the cloud drive turns a folder into
a ZIP. This guide explains what an advanced file transfer actually needs to do, which tools
deliver it for free, and when you really need an enterprise platform instead.

**Key facts**

- **Advanced file transfer** = large files, whole folders, several recipients, direct links, no sign-up, control over storage.
- **Free option:** StrongFolder sends files and folders browser to browser over WebRTC — No size limit set by StrongFolder. The practical limits are free disk space on the recipient's device, connection speed, and how long both devices stay online.
- **Folders keep their structure**; one link and a **QR code** serve several recipients.
- **Nothing is stored** on a server, and **no account** is needed on either side.
- **Enterprise MFT** is the right tool for scheduled, audited, system-to-system transfers.
- The P2P trade-off: **the sender's tab must stay open** until recipients finish.

## What does "advanced file transfer" mean?

There is no formal definition. In practice people mean a transfer that can do what an
attachment can't. We count seven capabilities:

1. **Huge files** — tens or hundreds of gigabytes, without a cap from the service.
2. **Whole folders** — subfolders and file names delivered intact, not zipped.
3. **Several recipients** — one link for a team, a client and a freelancer.
4. **Direct links** — no waiting for an upload before the recipient can start.
5. **Cross-device delivery** — a QR code from a computer to a phone, any operating system.
6. **No account** — neither side signs up for anything.
7. **Control over storage** — you decide whether a copy of the files lives on a server.

Basic tools usually manage two or three of these. Enterprise platforms manage most of them, at
enterprise prices.

## How do the main types of file transfer tools compare?

| Whole folders with structure | No | Usually ZIP | Online yes, ZIP on download | **Yes** | Yes |
| Upload before download | Yes | Yes | Yes | **No** | Yes, to the platform |
| Copy stored on a server | Yes | Yes, for days | Yes, until deleted | **No** | Yes, on managed servers |
| Several recipients | Yes | Yes | Yes | **Yes, one link** | Yes, with permissions |
| Account needed | Email account | Varies by service | Yes, for the sender | **No** | Yes |
| Works while sender is offline | Yes | Yes | Yes | **No** | Yes |
| Automation, audit logs, compliance reports | No | No | Some, on business plans | **No — built for people, not systems** | Yes |
| Price | Free | Free tier, paid upgrades | Free tier, paid storage | **Free** | Paid |

## How do I do an advanced file transfer for free?

With StrongFolder the steps above take under a minute. What makes the transfer "advanced" is
what happens under the hood:

- **Direct, encrypted connection.** Your browser connects to each recipient's browser over
  WebRTC. WebRTC encrypts every data channel with DTLS, so the file stream is encrypted in transit on every connection.
- **No upload, no storage.** Files are never uploaded to or stored on a StrongFolder server. To create the link and run the service, we keep transfer metadata: file and folder names, sizes and the number of files, plus the IP address and country of the sender and the country of each recipient.
- **Folders as folders.** Folders are sent as folders: subfolders and file names are kept, nothing is zipped. Saving a whole folder with its structure uses the File System Access API: Chrome, Edge, Opera and other Chromium browsers on a computer. Other browsers can download the files one by one or as a ZIP.
- **One link, many recipients.** One link can be opened by several recipients; each downloads directly from the sender.
- **QR code.** Every link also has a QR code, handy for sending from a computer to a phone.
- **Two ways to start.** Web app at strongfolder.com and the free Chrome extension StrongFolder — File Share; the extension is available in
  52 languages.

## What does managed file transfer (MFT) add?

MFT platforms are built for organisations that move files between **systems** and
**partners**, not just between people. Typical capabilities:

- **Automation** — scheduled and event-triggered transfers, retries, workflows.
- **Protocols** — SFTP, FTPS, AS2 and APIs for system integration.
- **Governance** — user roles, approvals, audit trails, reports for auditors.
- **Retention** — policies for how long files stay and who can see them.

If your requirement is "every night, push the sales files to our bank's SFTP server and log
it", you need MFT. If it is "get these 80 GB of footage to the editor today", you don't.

There is also a third category — **accelerated transfer** services aimed at media companies
(for example IBM Aspera, Signiant or MASV). They use optimised protocols to move very large
files over long distances and are paid. Check each vendor's current plans if this is your
daily workload.

## How do I get the best results with large transfers?

- **Use a wired connection** for transfers longer than an hour.
- **Turn off sleep** and keep the laptop on power: the files come from your device.
- **Check the recipient's free disk space** before sending hundreds of gigabytes.
- **Use Chrome, Edge or another Chromium browser on a computer** on both sides, especially
  when the recipient needs to save a whole folder.
- **Stagger recipients** on a slow upload: several simultaneous downloads share your
  bandwidth.

Realistic times for 100 GB at different upload speeds are in

## When is StrongFolder not the right advanced file transfer tool?

- **You need transfers to run unattended** on a schedule or between servers — use MFT.
- **You must prove who downloaded what and when** for an auditor — use a platform with audit
  logs.
- **You can't keep your computer online** while recipients download — use a cloud drive or a
  transfer service that stores the files.
- **Recipients will download over days or weeks.** The link works while the sender keeps sharing. When the sender clicks Stop Sharing or closes the tab, the files are no longer available.

## Summary

Advanced file transfer is about capabilities, not complexity: huge files, folders with their
structure, several recipients, direct links, no accounts and no stored copies. For
person-to-person delivery a free browser tool like StrongFolder covers all of that, at the cost
of keeping your tab open. For automated, audited flows between systems, choose an MFT
platform. Next: [how to send large files](https://help.strongfolder.com/en/guides/send-large-files/),

## FAQ

### What is advanced file transfer?

It is file transfer with capabilities beyond a basic attachment or upload: very large files, whole folders with structure, several recipients, direct links and QR codes, no account requirement, and control over where the files are stored. In companies the term also covers managed file transfer (MFT) with automation and audit logs.

### Is there a free advanced file transfer tool?

Yes. StrongFolder is free and runs in the browser: No size limit set by StrongFolder. The practical limits are free disk space on the recipient's device, connection speed, and how long both devices stay online. Folders are sent as folders: subfolders and file names are kept, nothing is zipped. No account is needed to send or receive.

### What is the difference between file sharing and managed file transfer (MFT)?

File sharing tools help people send files to other people. MFT platforms move files between systems and partners on a schedule, over protocols such as SFTP, with access control, audit trails and reporting for compliance. They are usually paid and administered by IT.

### Can I send files to several people with one link?

One link can be opened by several recipients; each downloads directly from the sender. Each download uses the sender's upload bandwidth, so simultaneous recipients share the speed.

### Do I need an account to use StrongFolder?

No account needed to send or receive.

### What are the limitations of a peer-to-peer transfer?

The sender's browser tab must stay open and online until the recipient finishes downloading — files come from the sender's device, not from a server. The link works while the sender keeps sharing. When the sender clicks Stop Sharing or closes the tab, the files are no longer available.
