thank you

The single-request approach is a ticking time bomb for max_execution_time and memory exhaustion. Once users start dropping gigabytes of files, your server will choke and browser connections will timeout. You can use Chunked Uploads or Asynchronous Processing

I’m building a Laravel 12 folder organizer where users may upload large folders (many files / large sizes), and I categorize files by extension and generate a ZIP for download.

Current approach:

Process everything in one request

Loop through uploaded files once

Add files directly from PHP temp upload paths into a ZIP using ZipArchive::addFile()

For large folder uploads, what’s the best approach for performance and scalability?

Also, what would you do specifically to speed up processing for large uploads?
