thanks for your suggestion , but the concern is since the source file is huge wont it cause memory issues if i open the file for reading the rows?

    anujajoseph:

    If the source file is too large to fit into memory, then the second suggestion might be better. But since computers tend to have so much RAM nowadays, most files will fit into memory.

    Update: On rereading the thread, I realize that in my first post I left out a word in the second suggestion. It should be an array of line numbers.
