Me too! Thank you for sharing this.
Great script. Thanks a lot.
The only thing is that it also removes boot.py, which is probably not desirable.
I have adjusted the script a bit to remove all the files from the board except boot.py:
import os
try:
import machine
except ImportError:
print('This script can only be run on a MicroPython device')
exit(1)
def delete_all_files_and_directories(directory):
for file_info in os.ilistdir(directory):
file_name, file_type = file_info[0:2]
if file_name == 'boot.py':
continue
file_full_name = f"{directory}/{file_name}"
print(f"Remove {file_full_name}")
if file_type == 0x8000: # file
os.remove(file_full_name)
else:
delete_all_files_and_directories(file_full_name)
os.rmdir(file_full_name)
delete_all_files_and_directories("/")
