Hi guys
How are you? Sorry, could you help me to create a new folder. I am making one device so it sends raw data into my SD card and saves this data into SD card. So when it sends data this time my program must first create a new folder and save this data into this folder. I tried a lot but couldn't succeed. Is it possible or not? If it is possible please help me? Thank you beforehand. Fahriddin.
