IZArc
This archive utility supports many archive formats like: 7-ZIP, A, ACE, ARC, ARJ, B64, BH, BIN, BZ2, BZA, C2D, CAB, CDI, CPIO, DEB, ENC, GCA, GZ, GZA, HA, IMG, ISO, JAR, LHA, LIB, LZH, MDF, MBF, MIM, NRG, PAK, PDI, PK3, RAR, RPM, TAR, TAZ, TBZ, TGZ, TZ, UUE, WAR, XXE, YZ1, Z, ZIP, ZOO. Regardless to say, it supports more formats than any other out there and its much faster than Windows XP's built in ZIP extractor.
7-Zip
Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR. Unpacking only: RAR, CAB, ARJ, LZH, CHM, Z, CPIO, RPM and DEB. It also has a little better compression ratio on some formats than WinZip has.
