I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Appending to a file is an efficient operation.  There's no similar efficient way to prepend data to a file.  You just have to create a new file, write the new data to the new file, then copy the rest of the old file onto the end of the new file.
