Bulldoser downloads any targeted file series from the internet and optionally encrypts image files to its own secure format. The image viewer & slideshow can view standard images and also view and en/decrypt this secure format. Bulldoser just downloads the file series you specify with various options. It has different modes: interactive, create download lists, process lists, and can also be used with a scheduler. There is optional password protection on startup & files can be erased (better than delete). It can download from password protected sites. See the product home page for more details.
