A good archive solution
One of the best archive tools that I have come across is IZArc and it supports almost every archive format available at the moment.
What I find most useful is the fact that you can you can use the tool to open CD image files like ISO, BIN, CDI and NRG and the tool can also be used as a converter for those files, say convert from BIN to ISO.
However, this tool is only available for the Windows platform including Windows Vista and on Ubuntu File Roller might be the option for a tool with a graphical user interface.
Another file archiver that I also use is 7-Zip
which is also open source and the developers say that there is a port of the
command line version to Linux.
