While highly efficient for standard operations, this process demands significant server resources. To protect the host system from crashing, system administrators place strict caps on how much data can be processed at once. Root Causes of the Error

“Error: Total size of requested files is too large for ZipOnTheFly.”

The error message appears when the combined size of the files you've selected for compression exceeds a specific limit configured on your server. While the exact threshold varies, it is commonly caused by several overlapping restrictions:

Instead of zipping files "on the fly" during an active HTTP request: Implement an asynchronous "Request ZIP" button.

For large collections (like the Playstation North America Collection), wget is the preferred tool. It downloads files individually rather than requiring a combined zip file.

Instead of building the entire ZIP in memory, stream the output directly to the user.

Ensure your compression library supports ZIP64, which lifts the traditional 4 GB zip archive limitation.

Instead of downloading a master folder, open it and download sub-folders individually.

In Nextcloud, dynamic zipping is managed by the Streamer component. If users hit this limit, you must adjust your config.php file. Open your Nextcloud configuration file: nano /var/www/nextcloud/config/config.php Use code with caution.
