Is there any way to sort the files correctly instead of: Title1 Title10 Title11 Title12 … Title2 Title20 … It’s really anoying when listening to music or watch pictures, that these don’t come in the correct order. For me this is a very big issue… I hope someone has an idea!

Not the most elegant solution (though probably the most common), but you could just name things like this: Title01 Title02 (…) Title10 Title11 Then they would sort in the correct order without any issues.
