ACDSee features an attractive, effective and easy-to-use interface, including toolbars, status bars and on-line help. It includes support for most BMP, GIF, JPEG, PCX, Photo-CD, PNG, TGA and TIFF files. With rapid JPEG decoding, and fast, full-color image previews, its file system browser front end lets you quickly browse through your images and other files. More features include fast scrolling and zooming, even during a decoding process, and an innovative system for deleting, renaming, copying and moving files. The automatic or manual slideshow has optional read-ahead decompression, always-on-top and full-screen viewing window options, and a shrink image to fit window or screen option. An optional single-instance mode makes ACDSee the perfect viewer for use as a helper application.
