Total Size Of Requested Files Is Too Large For Zip-on-the-fly · Tested & Working

| Constraint | Naive Behavior | Failure Threshold | | :--- | :--- | :--- | | | Stores entire ZIP in RAM | Typically 128MB - 2GB | | Execution Timeout | Blocks until complete | 30-300 seconds (web servers) | | Disk Space | Uses temp files | /tmp fills up | | Central Directory | Must be written after all file data | Requires seekable storage |

The central directory is the key: a ZIP file’s table of contents is at the end of the file. Most libraries cannot stream it without first knowing all file sizes and CRCs. 4.1 Level 1: Streamed Passthrough (No Compression – "Store" Method) Best for: Already compressed files (JPEG, MP4, PDFs). | Constraint | Naive Behavior | Failure Threshold

Use ZIP’s "store" method (deflation level 0). The CRC and size are known per file before writing. Use ZIP’s "store" method (deflation level 0)
