In Microsoft WORD 2003 why does it sometimes create a file called "~$antindex.doc" when I have a file called "Plantindex.doc"?

This is the owner file, containing the name of the person working on a document to prevent others from editing concurrently.

Microsoft says:

Owner File (Same Directory as Source File)

When a previously saved file is opened for editing, for printing, or for review, Word creates a temporary file that has a .doc file name extension. This file name extension begins with a tilde (~) that is followed by a dollar sign ($) that is followed by the remainder of the original file name. This temporary file holds the logon name of person who opens the file. This temporary file is called the "owner file."

When you try to open a file that is available on a network and that is already opened by someone else, this file supplies the user name for the following error message:

This file is already opened by user name. Would you like to make a copy of this file for your use?

Curious what happens if two users open files which differ only by the first two characters in their names... – grawity Sep 11 '11 at 12:24
