How to delete all files in a directory?

Hi

I have setup a FAT filesystem where I want to be able to delete a whole directory and everything in it (subfolder, files, etc).
sspec_rmdir() only works on empty directory and sspec_delete() only works on files, not directories.

How do I delete the directory and the whole contents?
One option is to use nested for-loops since I would probably only use three levels of subdirectories but there must be a simpler and better way.

BR,
Anders
