You can do it fairly easily via the EXPORT command. I don't have a copy of Access 2007 to hand so I can't tell you precisely, but on Access 2003, EXPORT is on the file menu. Select the export location and the file type (text) and click on Export All. You will then be presented with a wizard which will ask you a few questions including as what delimeter (eg Tab, Comma etc) you wish to use.
