[SOLVED] Is there anyway to have a filesystem-like facility on ESP8266?

...indeed, one learns what the 'economic needs' - or - the market(s) dictate... just a little bit screwed, because 'the markets' are made and that mostly by non-engineers... leading to 'rabbit trails'. Because something is 'fashion', most go down these trails kudo-ing one another and many good things get thrown out... luckily, later, some of the discards recover and are picked up in one or the other way when returning to a more straight path... and luckily too: once in a while along the rabbit trails, some other good things are discovered as well...
