You might want to try somewthign a little more universal. WinRAR and WinACE are used quite often. Try making them exe's so the users don't need any programs to rebuild them. WinRAR supports RAR and ZIP and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR and ISO archives, while WinACE supports ACE, ZIP, LHA, MS-CAB, JAVA JAR and can extract ACE, ZIP, LHA, MS-CAB, RAR, ARC, ARJ, GZip, TAR, ZOO and JAR.
