On this issue, I found that the code above when I set it, did not work for anything larger than 20MB the zip test would come back "empty"

.
I am not sure if it was because my .htaccess on the main site, already had some coding in. The system may have been detecting something different, so I put a new .htaccess in with the following from another site:
php_value upload_max_filesize 200M
php_value post_max_size 200M
php_value memory_limit 200M
I uploaded a 31.5mb file and tested the return link in the admin products, and got the zip back "Complete"
