C ben TXT-be valo irás, neirja felul a letezo fajlokat - valami otlet hogyan oldajam meg?

koszi mar vegre sikerulni latszik...itt a kod ha kene valakinek majd...sok feles dolog van benne, probalkozasok stb...

de vegulis az mukodes:

kell hogy legyen egy output subfolder a program ahol fut.

es itt mindig letrehoz egy ido szerinti mappat,majd ide menti majd a dolgokat(txt-t)
