breaking up large text file

[spuppett]

Does anyone know how I could go about breaking up a large (770 mb) text file into smaller files?

I can't seem to find any ideas anywhere. I have a file, that contain archived emails. I need to parse them into their indivdual emails. i know how to do that part of it, but I in-order for that method to work, I need to be able to start reading from a specified location in the file, which I don't know how to do, or replace the section I've already read with a nullstring, which I don't know how to do either. The file is obviosly too big to fit in a variable, which is what I have been doing with this project.

Any one have any suggestions or ideas??

Why not open them up in your email program and then create separate email boxes to move them to?

If they're sequential files, you'll read the data in differently than if they're not. Not knowing what email program you've stored them from, if any, makes it difficult to answer your question.

They are outlook .mbx files. The reason that I'm doing this is that my boss is trying to get away from Outlook for archiving, for what ever reason, and also I'm putting them in a db so that we can query and look stuff up quickly.

I've gotten this to work really well on smaller files. The only problem I'm having is that this file is too big to store in a string, so I need to break it apart, but I can't do it arbitraily, as I don't want 1 email in 2 diffrent files.

Thank you for your reply.

Here are a couple links for programs that handle this:

If you really want to do this yourself, here's a link to a place that has the MBX format for you (plus the formats of many more files):
