Reproduction

Diagnostics
Hi @OpenAI_Support,
Unfortunately, the issue remains unresolved for me after the fix announced in post #16. My earlier report is post #15.
I have requested fresh exports, but I still cannot obtain a usable archive. The latest local ZIP file inspected on October 22, 2026 was empty (0 bytes).
Could you please investigate this as an unresolved case and check export generation and delivery for my account? If the download issue cannot be resolved, is there an alternative way to obtain a complete export?
I’m experiencing the same issue with my ChatGPT data export on October 23, 2026.
I’ve downloaded the same export multiple times using Chrome and Firefox on Windows 11.
The resulting ZIP files vary significantly in size, from approximately 663 MB to 3 GB.
All downloads appear to complete normally, but both WinRAR and 7-Zip fail to open the archives.
I also inspected the ZIP structure using PowerShell. The files contain the expected ZIP header (50 4B 03 04), but the end-of-central-directory signature (50 4B 05 06) is missing from the files examined.
This strongly suggests incomplete or truncated archives.
I’ve already attempted to contact support, but the automated assistant only redirects me to basic data export instructions.
Could the OpenAI team investigate whether the export delivery issue remains unresolved for large archives?
I’d also appreciate an alternative method to obtain my complete data export if the current delivery mechanism cannot handle it reliably.
