Question

I am trying to upload a 4.8 GB file using jQuery transmit plugin and SWFUpload. I am able to upload a file size 2.5 GB.

Is there any system restriction on file upload?

I am using a 64-bit system.

Answer 1

It could also be a limitation in php.ini.

"Clarification on the MAX_FILE_SIZE hidden form field: PHP has the
somewhat strange feature of checking multiple "maximum file sizes".
The two widely known limits are the php.ini settings "post_max_size"
and "upload_max_size", which in combination impose a hard limit on the
maximum amount of data that can be received."
