STM32F429I-DISC1 How to read files written through STLink USB port?

When the DISC1 board is connect to a Windows PC, it is seen as MSC USB drive of 2MB capacity, labeled "DIS_F429ZI".

I can write files to it and they are readable from Windows.

I assume the files are stored in the STM32F429 internal flash since the capacity matches.

 

Is there a way to access these files from the STM32F429I microcontroller?

I know I can access the flash memory - but how can I locate the files in it?

 

I suppose the STM32F103 microcontroller that runs STLink is handling the file system for this, hence the files "disappear" after power cycle (unplugging STLink cable). However, I guess it is still writing the files to some predetermined location in the flash.

 

I could not find any examples for this or maybe I'm searching for wrong terms ...

Does anyone have any info about this?
