If you’ve ever had a client say “the attachment bounced,” you know large‑file delivery can derail an otherwise smooth project. Email caps, broken links, wrong versions, and security concerns all add friction—and damage trust. This guide shows a clean, repeatable way to deliver large files that feels professional every time.

What “professional” file delivery looks like

Professional isn’t about fancy tools—it’s about clarity and confidence:

Clear: The client knows exactly what they’re receiving and how to access it
Secure: Access is limited to the intended recipient(s)
Reliable: Links work across devices and don’t linger forever
Traceable: You can tell if/when it’s been downloaded (or control it with limits)
On‑brand: The experience feels thoughtful and tidy

Choose the right delivery method

Different handoffs call for different approaches:

Temporary, one‑off handoff (most client deliveries): Use a secure, time‑limited link with a passcode and download limits. This keeps the file from lingering online.
Ongoing collaboration: Use your team’s shared drive, but still hand off “finals” via a time‑limited link to avoid confusion later.
Very large or archival assets: Share a preview/approved export via link, and keep raw assets in longer‑term storage.

With Comfyfile, you can share up to 4GB anonymously with optional password protection, link expiry, and download limits—no account required. That covers most professional handoffs without extra setup.

Prepare your file like a pro

A few minutes of preparation saves hours of back‑and‑forth:

Export the right format
- Video: H.264/HEVC MP4 for review; ProRes or DNxHR if client requested
- Design: PDF for approval; native file for handoff if agreed (e.g., Figma export, .PSD, .AI)
- Code/artifacts: Zip the deliverables with a README and version
Compress sensibly
- Use lossless or visually lossless settings for review exports
- Remove extra layers/metadata the client doesn’t need
Package assets
- Zip folders so nothing goes missing in transit
- Include fonts/licenses if required and agreed
Name it clearly
- project-name_deliverable_v1-final.ext
- Avoid spaces and special characters; use hyphens/underscores

Create a clean, secure link (step‑by‑step)

Here’s a simple handoff flow using Comfyfile:

Upload your file (or a zip if multiple files) — up to 4GB
Add a password/passcode
Set an expiry (e.g., 7 days for paid; up to 24 hours on free uploads)
Limit downloads (e.g., 2–3 total) to prevent oversharing
Add a short note (what the file is, version, any instructions)
Copy the link and share it in your client thread or email
Send the password via a different channel (e.g., text or Slack DM)

Why it works:

Expiry reduces long‑term exposure
Password protects against forwarded links
Download limits keep distribution under control
A clear note avoids “what is this?” replies

Include a professional handoff message

Use a short template in your email or chat to set expectations:

Subject: Final deliverables – Project X v1

Hi [Name],

Here are the final deliverables for Project X. The link below will expire on [DATE]. I’ve limited downloads to [N] for safety.

Link: [PASTE LINK] Passcode: [SEND SEPARATELY]

What’s inside:

[File/Folder name] – Final export (v1)
[Optional] README – notes on color/profile/fonts

If anything needs a tweak, reply here and I’ll share a fresh, updated link.

Thanks, [Your Name]

Avoid common pitfalls

Don’t reuse old links: Upload a new version and send a fresh link for any revision
Don’t mix channels: Keep discussion in one thread, and send passcodes in a separate channel
Don’t leave links alive forever: Use expiry by default
Don’t assume the client’s environment: Add a lightweight preview or PDF when appropriate

Troubleshooting (to copy/paste)

“The link won’t open.” → Try another browser or device; ensure the link isn’t truncated
“It asks for a passcode.” → Use the passcode I sent in a separate message; it’s case‑sensitive
“Download is slow.” → I can provide a lighter preview export; let me know
“Can I forward this?” → Please don’t; I can generate a separate link for others

FAQ

How big can my file be? Up to 4GB per upload for free, anonymous sharing
Do recipients need an account? No—clients can download without creating an account
Can I control access? Yes—set a passcode, expiry, and total download limit
What happens after expiry or max downloads? The link stops working and the files are removed

When to use a drive instead

Use your team’s drive (Google Drive, Dropbox, etc.) when the client needs ongoing collaboration or a shared working folder. For final deliveries and approvals, a clean, expiring link keeps everything simple and reduces long‑term risk.

Professional delivery is about reducing friction and maintaining trust. A short checklist—right format, clear naming, secure link, concise handoff note—goes a long way. When you’re ready to send, use Comfyfile to share a polished, password‑protected link with expiry and download limits.
