Some filename can not put.

Env:

Windows 10
Anaconda 3
Both NodeMCU ESP8266 And ESP32
MicroPython latest version

I have a python file named Ultrasonic.py.
And when I do next command:

python -m mp.mpfshell -o COM5
md ezmpy
cd ezmpy
put Ultrasonic.py

There have an Error:

Traceback (most recent call last):

And if I rename Ultrasonic.py to u.py, and retry, it is all good, no error.
I met many times this problem, sometimes is Ultrasonic.py, sometimes is finger.py

well.
From the picture can know this error is come from the board returns information on the error.

Do not use the python -m mp. Mpfshell directly because the lpwd path of mpfshell is not consistent with the path of your file.

execute mpfshell directly, or check the directory returned by the lpwd of the board. If you're windwos, you also need to be aware that it's under the same drive and filename uppercase.

You can also try out my mpfshell. XD.
