After downloading a file to an ESP8266 the 'dir' command fails

[PlasmaSoftUK]

After downloading a file to my ESP8266 I see the following error, I think all it needs is the 'import os' before executing the os.listdir('.') command:

`Ready to download this file,please wait!
..........
download ok

os.listdir('.')
Traceback (most recent call last):
File "", line 1, in
NameError: name 'os' is not defined

`

uPyCraft will import os automatically when you open tools->serial, and both os.listdir("."), os.listdir() run well. When the software is connected to the developing board, reset the board, then you need to import os by hand. While you need not to import os when connect the serial port via tools->serial or the icon connect/disconnect.

I found that uos.listdir('.') instread of os.listdir('.') does work...
