Question about iTunes library

Hi there friends ! Got a question , i want to ask can i somehow just drag and drop my music folder to itunes and that in i tunes it was an playlist , and if folder contains some folders in it it creates an music folder with librarys ?

Not sure what you are getting at, but if you drag your tracks (in a folder, or by selecting them one by one) into the playlist sidebar, the tracks are added to the library as well as a new playlist is created. Not sure about your folder thing though, I think it just creates one playlist and includes every song that's included in it.
