 Q:

C# linq Files.ReadAllLines() fails for large 650MB CSV file

The following code works when I work with CSV files under 1MB but fails when I try to read 600MB file. Any reason why? Or any fixes?  
What I am trying to do is read a large raw CSV file in Visual C# 2010 and manipulate the contents, could be line by line or to memory at one go and export 5 files with certain selections using LINQ. These 5 files are to be used in various processes so need them to be split into 5 different files with very different content.
When the file is small the codes work perfect but when it's too big it gives me the messagebox from Exception handling "Cannot write to source destination". I have tried both ReadAllLines() and ReadLines() Please could you advise me. Thanks.
