Reading multiples text files from a folder and converting them to an exampleset ?

I have a folder that contains multiple text files. So how can we read the content of each file and use them as a row in the exampleset.

for ex : 

for a folder with 5 text files the exampleset will look like.

| Row |    TextContent    |

-------  | ---------------------

1        | contents of fille1

2        | contents of fille2

3        | contents of fille3

4        | contents of fille4

5        | contents of fille5
