I've been taking a look at the SPIFFS example from the Arduino core, in particular to the listDir function:
https://github.com/espressif/arduino-es ... est.ino#L9
I've noticed that the procedure doesn't make any call to the close method. It just keeps calling the openNextFile method until there are no more files available.
Isn't a call to the close method needed to make sure no resources are left hanging?
I've taken a look at the implementation of the openNextFile function in the Arduino core, but it doesn't seem to be doing any implicit call to close the file:
https://github.com/espressif/arduino-es ... i.cpp#L384
Nonetheless, I'm not sure what happens in the lower layers (IDF / SPIFFS).
It would be awesome if someone could help clarifying this
Best regards,
