os.execute("mkdir " ..path) failed

I want to create a directory in system.TemporaryDirectory.
the code is bellow:
local path = system.pathForFile( “m123//”, system.TemporaryDirectory )
print(path)
os.execute("mkdir " …path)
but the code can’t create the directory, why?

http://developer.anscamobile.com/reference/index/osexecute :
This function is only available in the Corona simulator. It does not work on the device.

Not entirely sure if Corona supports directory creation, can’t see it in the File/IO docs: http://developer.anscamobile.com/content/file-io [import]uid: 11393 topic_id: 10962 reply_id: 40141[/import]

Nope. Sandbox will break all sorts of restrictions and you could run the risk of getting your app banned.
