It contains encoded bitmap data so that the downloaded image appears progressively from a blurry picture to the final sharp image. PJPEG files may also fill alternating horizontal lines until the full picture is revealed.
 - X-Motif UIL Table (UIL) is a plain text file format used by the User Interface Language (UIL) compiler, which is used for creating user interfaces for the X Window System.
