What is the advantage of using Path.Combine over concatenating strings with '+'?

Question

I don\'t quite see the difference.

What could Path.Combine do better than perfectly working string concatenation?

I guess it\'s doing something

According to this documentation Path.Combine internally performs a string concatenation using +-Operator.

 private static String CombineNoChecks(String path1, String path2) {
        if (path2.Length == 0)
            return path1;

        if (path1.Length == 0)
            return path2;

        if (IsPathRooted(path2))
            return path2;

        char ch = path1[path1.Length - 1];
        if (ch != DirectorySeparatorChar && ch != AltDirectorySeparatorChar && ch != VolumeSeparatorChar) 
            return path1 + DirectorySeparatorCharAsString + path2;
        return path1 + path2;
    }
