to clarify his point -- some issues come with Memo or General field::
* memo file bloat -- when you change the contents of Memo or General, the old data stays there and new data gets tacked on at the end, if the contents of the Memo or General fields changes frequently, you may find that most of the file consists of unreferenced data.
* memo file corruption
* 2GB limit on files.
