UDF Media Reader reads disks created by packet-writing programs like DirectCD. Mac OS X 10.0 through 10.4.5 mounts UDF+VAT disks using their ISO 9660 information, but a bug causes it to silently truncate the beginning of files which cross packet gaps. UDF Media Reader is a Cocoa program that analyzes a UDF disk, presents its contents as a directory tree, and allows the user to copy all or part of the disk's contents to the host filesystem. It has been tested with CD-Rs created by DirectCD on Windows 9x. It will probably work with CD-Rs created by InCD, and it might work with Sony Mavica CD-Rs.
QuickStep is a fast, simple image viewer. It can read JPG, PNG, GIF, and TIFF images. It can locate and display images of those types within ZIP, RAR, and TAR archives. QuickStep can be started from the Finder but is also designed to work well when started from a terminal. It is keyboard friendly: most commands use single keystrokes instead of Command-key combinations. It can display images fullscreen and run a slideshow.
