In this popup you can find some supporting utilities. In UniView, there are several built-in functions, that you can use:
Batch conversion - executes utility to convert many file at once
Capture - executes utility for screen capturing
Slideshow - executes utility for making simple images presentations
Thumbnailer - executes utility for thumbnails generating Other utilities (called plugins) can you download from my homepage or from pages of other third-party producers. You can also create your own plugins (if you have UNIVIEW PLUGIN SDK). Help for these function is not my work - ask authors if you can't find any!
