2. how will you come to know, whether file is empty or not.

Open the file in browse/view/edit mode thru option 3.4 on ISPF panel... if you are able to open it is not empty.
If you meant in COBOL... READ the file, AT END "DISPLAY FILE OVER"...
If you meant in a JCL... Look here...

3. what is internal reader?

You use Internal Reader to execute a JCL statement thru COBOL program.

Use TSO Allocate Command to create dataset in COBOL Program.
Also look here...
