How to Download Large Collections

Online Aviation Library — Download Guide


Why am I seeing "System cannot zip files above 1GB"?

Our largest collections contain thousands of original engineering documents and can exceed 1GB in total size. Due to a technical limitation, files above 1GB cannot be bundled into a single ZIP download. This is normal and your files are fully accessible.


How to download your files — step by step

  1. Open your order confirmation email and click the Download button
  2. On the download page, do not click "Download All"
  3. Click each file individually to download them one at a time
  4. Save each file into a dedicated folder on your desktop as you go
  5. Once all files are downloaded, your collection is complete

Tips for large collections

  • Use a desktop or laptop — mobile devices may struggle with large files
  • Make sure you have enough free disk space before starting
  • Use a stable internet connection — Wi-Fi is recommended for large archives
  • If a download fails mid-way, simply click that file again to restart it
