How to read values from multiple text files and then save it

Hi Chandu, Thanks for the reply.  

I saw the code in the provided link. it actually points to a specific file.

In my case, I will not know the file name upfront. All I know is multiple Employee details will be stored as .txt file in one particular location. Now I need to read each file, then get the required information within the file and store into Database.

Now I do not know how to read these text files and get the details.

Can you please help me on this.
