ZipGenius (as you may understand) gives full control on zip files and archives similar to zip, plus it can protect your zip files with a better encryption system than the one you normally activate by adding files with password. CZIP file type can be read just by ZipGenius 1.4 or later, or by program compliant with CZIP format.
Here are the other file formats supported:
ZIP / CZIP, JAR, 7z, EAR, WAR, XPI, PK3, SQX: all functions
CAB
RAR, ACE, TAR, TAZ, TGZ, GZ, Z, BZ2: these files can be just read and decompressed by ZipGenius. Compression is not supported because their algorhythm is not available to third parties.
