How to transfer 2M Bytes of data via USB-VCP of STM32F429 MCU?

I need to transfer 2 M Bytes of data via USB virtual com port of STM32F429 microcontroller, withing 2-4 seconds.

I am using the USB standard libraries available on ST website. I have successfully transfered small strings, But when it comes to the large data.

So why can't you transfer long strings? I should be functionally the same as small string, except you'll need to buffer and wait for the previous transfer to complete before sending more.

Thank you for replying

Can you tell me which function can be used to check whether precious transfer is complete.

I am using "STM32F USB Drivers & Liberary". So is there any library that contains such a function to check a flag for data transfer complete?
