Copy File Name And Contents Of That File In A Specified Path?

I just found a code to copy file path and file contents. However it is copying folder path and folder contents.here is my requirement.I will specify a path, macro has to copy that file name in a particular cell, then it has to copy all its contents.
ex:

file name 1 has 3 sub files in it, file name 2 has 2 sub files in it--

column AColumn B
file name1file contents
file name1file contents
file name1file contents
file name2file contents
file name2file contents

And also i have extend this macro to write a index function. i will tell u about this. but first i need above thing I researched but I didn't find.

I need file name in a column then i need file contents in b column.

if a file has 10 file contents in a file then that file name should come 10 times in a column, and in b column all its contents.
