I'm not sure what sort of files have the extension of .AUW, but it sounds like the relevant program is renaming the file for some reason. One possibility is simply to create a backup in case of a crash or other problem. While it's certainly possible to rename these files, you might want to look further into why they're getting changed - or why the original file (with the.AUW extension) isn't present.
