Videonics PowerScript
File Names and File
Type Extensions
While working with PowerScript, you work with different types of files. (Files store infor-
mation and other data that PowerScript needs to operate.) PowerScript uses a standard
computer-based scheme (known as the "DOS File Naming Convention") for naming files.
File names consist of eight characters, followed by a period, followed by a three character
file type extension. The eight character limit means you need to be creative coming up
with meaningful file names. On the other hand, you can use only pre-defined character
combinations as file type extensions because these extensions tell PowerScript what the
file contains and how to use it. This manual explains when and how to use file type
extensions. Examples of file names and extensions follow.
File Name and
Extension
CARTOONS.PRJ
LOGO.EPS
BOX1.APS
GOOMBA.JPG
MOONSHOT.PLA
STARTUP.PRJ
Description
Identifies a project file. The name of the project is CARTOONS.
The PRJ file type extension tells PowerScript this is a PRoJect
file.
Names a graphic file. The name of the file is LOGO. The EPS file
type extension tells PowerScript this is an Encapsulated
PostScript-type file.
Names a special type of EPS file. The file type (APS) indicates
that the file contains transparency information which allows
parts of the image to be transparent.
Names a graphic file. The name of the file is GOOMBA. The JPG
file type extension tells PowerScript this is a JPEG-type graphic
file.
An automatic playback file. The filename, MOONSHOT,
identifies a specific project. The PLA file type extension tells
PowerScript to automatically PLAy the project (in this case,
MOONSHOT.PRJ) when it receives the PLA file.
Identifies an automatic playback file. The file name, STARTUP,
identifies a special project that tells PowerScript to play the
project whenever it starts up. The PRJ file type extension, as
above, indicates this is a PRoJect file.
