Hi Rich, Thanks a lot. It might be WLM files since I recently installed that program. On that note, does anyone know how to change the sounds in Windows Live Messenger? I found the ones for Windows Messenger in the sounds folder in the control panel, but have not discovered how to do it for the Windows Live Messenger. As always, thanks for the help.

Try it again. Just in case it does not work for you it states it might be windows live messenger log files.

Press enter, and each record will be displayed in a table. HTH, Blake
