Nice to get a little bit of an idea of what's been going on the past three months, TRC time.
@SuperSailorYue: You might want to try
http://www.tugzip.com . It's an awesome freeware archiving program that supports: ZIP, 7-ZIP, A, ACE, ARC, ARJ, BH, BZ2, CAB, CPIO, DEB, GCA, GZ, IMP, JAR, LHA (LZH), LIB, RAR, RPM, SQX, TAR, TGZ, TBZ, TAZ, YZ1 and ZOO archives & supports BIN, C2D, IMG, ISO and NRG disc-images. I've been using it for a few years now and it has never failed me.
