thanks for your reply, I have used this option countless times already, in the faq it may work but in my system it doesn't.
it could be something wrong with my settings, lets go to my example above:
so what I have done many times is
- open folder "new music"
- click menu folder > folder options > set sorting by name (as I want the files listed inside the subfolders)
I then check that everything is saved and working ok, then I visit again the folder "new music" to change the sorting only for this folder "by date created" and I save only for the current folder and not the subfolders. However when I visit a music subfolder the sorting is messed up again to creation date.
