Required and automatic filename extensions.
There are two instances where file extensions are implied and/or required. Application-specific files (such as configuration files or look-up-tables) that are located in the v4/etc/ directory have standard extensions that are used to identify them to the applications. The image marking tool vdview also uses filename extensions to associate image annotations automatically with their original images.

For the standard VisionX image viewer a standard file name convention is used so that the annotations associated with a specific image file may be easily identified. Each annotation file is iedentified by a unique index number. Vdview automatically assigns the next available index number when saving an annotation file.
