Answer 5

There are factors to consider, for example, file system objects (files, directories) in modern O/Ses may be encrypted or compressed by system to prevent unauthorized access. And next, there are antivirus programs, which may presume your program was doing some aggresive action (read all files) and may take actions in attempt to keep safe the system.

I'm not trying to stop you in your way, just giving you a little points to consider.

If you can get Bruno's code to run, then you can turn it into a recursive function, which you can try as a test.

Anyways, good luck buddy! 👍
