mpyc is defined in mp/mpfshell.py lines 597...621.

mpfs [/]> help mpyc                                                                                   
mpyc <LOCAL PYTHON FILE>                                                                              
        Compile a Python file into byte-code by using mpy-cross (which needs to be in the path).      
        The compiled file has the same name as the original file but with extension '.mpy'.           

mpfs [/]> _

Some ports of MicroPython allow loading and execution of those precompiled files from the file system.

mpy-cross is part of the MicroPython source tree.

I've built and flashed MicroPython without the mentioned changes to one my NodeMCU Devkit clones and it does not load .mpy files from the file system.

A second clone has got the same MicroPython version with those changes added:

mpfs [/]> lls

Local files:

       port_config.py
       boot.py
       HelloPython.mpy
       HelloPython.py

mpfs [/]> put HelloPython.mpy
mpfs [/]> repl
>
*** Exit REPL with Ctrl+] ***

MicroPython v1.8.3-127-ge1e1014 on 2016-09-08; ESP module with ESP8266
Type "help()" for more information.
>>> import HelloPython
Hello, Python!
>>> os.listdir()
['boot.py', 'HelloPython.mpy']
>>> _

...there is no HelloPython.py so it must have executed HelloPython.mpy.

HelloPython.py is this oneliner:

print("Hello, Python!")

Ok... so this still is not a feature in all ports by default.

Thanks.
