Answer 1

You might be better off to use memory-mapped files handling here.. The memory mapped file support will be around in .NET 4 (I think...I heard that through someone else talking about it), hence this wrapper which uses p/invokes to do the same job..

Edit: See here on the MSDN for how it works, here's the blog entry indicating how it is done in the upcoming .NET 4 when it comes out as release. The link I have given earlier on is a wrapper around the pinvoke to achieve this. You can map the entire file into memory, and view it like a sliding window when scrolling through the file.
