ZipMagic 2000

From MacNode:

The best zip utility just got better! ZipMagic's cool patented ZipFolders technology actually lets you use Zip files without unzipping them, so you can access zipped files like normal Windows folders. ZipMagic also includes powerful options like automatically spanning Zip files onto multiple disks, creating self-extracting Zip files, opening several types of non-Zip compressed files and Email formats, a built-in graphics file viewer, and more. ZipMagic can open ZIP, ARJ, LZH, Z, GZ, TAR, RAR, PAK, ZOO, CAB, ARC and DWC files and decode MIME/Base64, BinHex, Uuencode and Xxencoded email formats.
