Effortless Ways to Deliver Heavy Zip Archives Without Failures
Sending large zip files can be a daunting task, especially when file size limits, slow upload speeds, and compatibility issues come into play. Whether you’re transferring high-resolution media, large codebases, or bundled project folders, knowing how to send large zip files without failures is crucial for smooth digital communication.
In this comprehensive guide, we’ll explore the best ways to send large zip archives reliably. From using cloud storage to file transfer tools, and understanding compression options, this article covers all your bases with practical tips and examples.
Why Large Zip Files Fail to Send
Before jumping into the solutions, it’s important to understand why sending large zip files can be problematic.
Common Reasons for Transfer Failures:
- Email Attachment Size Limits: Most email providers restrict attachments to 20–25MB.
- Timeouts and Interruptions: Upload or download processes may fail due to slow internet or server timeouts.
- Storage Quotas: Recipients may not have enough cloud storage to receive large files.
- Compression Limits: Some files, especially already compressed ones like videos, don’t shrink much when zipped.
- File Corruption: Uploading or downloading large files over unstable networks can result in corruption.
Best Practices to Send Large Zip Files
To avoid transfer issues and ensure smooth delivery, follow these best practices:
✅ Check File Size and Format
Before sending, double-check the actual size of your zip file. Use compression utilities like 7-Zip or WinRAR to possibly reduce size. Rename files or split them if needed.
🔎 Example: A 5GB folder of RAW images may compress down to 4.5GB using .zip or .7z formats. Still too large for email? Time to look at smarter solutions.

3. FTP and SFTP Servers
For enterprise users or developers, File Transfer Protocol (FTP) offers full control.
What You Need:
- FTP client like FileZilla or Cyberduck
- Access credentials to a remote server
- Knowledge of SFTP for encrypted transfers
Example: A video production house uses SFTP to upload 30GB zipped archives for client review.
Pros:
- No file size limits
- Great for routine large file transfers
- More secure with SFTP
Cons:
- Requires technical know-how
- Setup time and maintenance required
4. Peer-to-Peer File Sharing
Peer-to-peer (P2P) tools allow direct transfers without intermediaries.
Resilio Sync (formerly BitTorrent Sync)
- Uses BitTorrent technology
- No file size limits
- Encrypted end-to-end
- Requires both sender and receiver to install the software
Pros:
- Ultra-fast on local networks
- No third-party servers
- Secure
Cons:
- Steep learning curve
- Not suitable for occasional users
5. File Splitting + Compression
Break large zip files into smaller chunks using file-splitting tools.
Tools:
- 7-Zip: Split into custom volumes (e.g., 100MB, 500MB)
- WinRAR: Create multi-part archives
Example: Split a 4GB .zip file into eight 500MB parts to send via multiple emails or cloud uploads.
Pros:
- Circumvents upload limits
- Ideal for slower networks
Cons:
- Requires all parts for reconstruction
- May confuse recipients unfamiliar with multipart zips
6. USB Drive + Shipping (Old School, Still Useful)
In areas with poor internet or when legal/medical compliance demands physical transfer, a USB flash drive works.
Example: A legal team sends encrypted zip files on a 128GB flash drive via FedEx.
Pros:
- 100% offline
- Great for very large file sets
Cons:
- Slowest method
- Risk of physical loss or damage
Tips for Sending Large Zip Files Successfully
🛠️ Optimize File Size
- Use .7z or .rar formats for better compression
- Remove redundant files before zipping
- Avoid zipping already compressed files (e.g., .mp4, .jpg)
🔒 Add Security
- Encrypt your zip files with a strong password
- Use secure transfer platforms (SFTP, HTTPS links)
- Consider using tools like AxCrypt or Veracrypt for added protection
📩 Notify Recipients
- Always inform your recipient when the file has been sent
- Include download instructions and passwords separately
- Mention the expiration date if the platform has one
🧪 Test Before Sending
- Upload and download your file yourself
- Check if the file opens correctly and contains all needed items
- Ensure all split parts are complete if using multipart zips
