I've got a problem uploading files.

1.  I upload a file to a forum that uses the database.  It is a text file.  When I download the file I get a file that is exactly one byte larger than the file I uploaded.  There is a null byte stuck on the end.

2. I upload the same file to a forum that uses the filesystem for attachements.  It downloads exactly as uploaded.

-----------
I really need to use the database for file storage, and I really need the download file to be an exact copy of the original file -- without the extra null byte.

Help!
