Write/read a file from PC with code on Keil for STM32L100

Hi,

I would like to know if it is possible to write/read text in a file (.txt) saved in a PC directory by using the STM32L100 code. Knowing that the board is always connected to the PC with a USB cable.

Thank you in advance for your help.

Is it possible to create the app and communicate with the USB knowing that there's no Virtual Com Port available for the STM32L100?

sure - you'd just have to work with whatever USB device profile(s) is/are available
