Hi ,

How to create a folder on SD card using Microcontroller ? I have implemented a FAT32 system on my SD card. I can do normal read/write operations. Also I am able to create normal .txt, .xls files etc. But how I can create a folder?

Post your code. Which compiler are you using? Are you using any libraries for SC card code. If yes, there will be functions for directory creation like f_mkdir(), etc...

I am using AVR studio AVR-GCC compiler.

I dont have any function to make directory. Yes but I have a function to write a file which creates file if required.

Two options:
- use a FAT32 library that includes subdirectory managment
- make your own library functions, referring to the FAT32 specification downloadable from Microssoft
