If you're running 64-bit PHP, you should be OK.  However, this problem still exists in 32-bit PHP.  See the warning in the PHP manual: [URL]
According to EsuHelpers.php and public function createObjectFromFile, there is a comment highlighted currently fails on file size > 2GB, is this still valid? We are working on PHP version's API to support for file size upload >2GB, please share your experience is PHP able to support?          public function createObjectFromFile( $file, $acl = null, $metadata = null ) {                  $fd = [NAME]( $file, 'rb' );                 if( $fd === false ) {                          throw new EsuException( "Could not open file \"$file\"" );                 }                 $b = filesize( $file );                 if( $b > 0 ) { // PHP currently fails >2GB                         $this->totalBytes = $b;                 }                 return $this->createObjectFromStream( $fd, $acl, $metadata, true );         }  Thank you.
