Filaments are features associated with magnetic flux inversion boundaries. Such boundaries occur inside or between active region and around the polar cap. The TRACE satellite has observed numerous filaments and similarities between all of them have been noted. In particular there are fine structured flows alone filaments and when filaments are activated there are loops over the flux inversion boundaries that range from perpendicular to the filament to highly oblique - sheared loops. Often active region filaments have a characteristic S shape. This poster presents example TRACE movies that illustrate the above mentioned features of filaments. Also presented are a series of potential field models of flux inversion lines and pairs of flux inversion lines (quadpole configurations) that have many of the features that are seen in the TRACE movies.
