Unix tip: 7-Zip to the rescue | ITworld
Convenience - Options to extract one or multiple archives from Windows Explorer and to open extracted folders after extraction. Other features - Unicode support is a must, as are options to customize the context menu and other program features. Bandizip ticks all those boxes. The program supports 37 different file formats at the time of writing including all major archive file formats but also disc image formats such as ISO or IMG. The application is available as a portable version or setup for Windows as well as a (paid) version for Apple's Macintosh system. If you install the program on Windows, the file association settings page is opened right afterwards. Here you can associate archive file formats to open with the application. Doing so will replace the icon of associated archives with the Bandizip icon. It also allows you to double-click the archive to run an action configured in Bandizip on it. One interesting feature of the application is the ability to change what happens when you double-click archives.

7-Zip (64-bit version) | PCWorld
In fact, they often make it into a verbmuch like we Google things on the Internet, we zip files before sending them over email. ZIP is just one compression format, though, and it isnt necessarily the best. Free, open-source utility 7-Zip supports ZIP, but also the much-improved 7z compression format. In fact, 7-Zip is the official reference implementation for the 7z format, and since it is open source, the format specification is distributed right within the source code. To test it, I used a folder with 65MB of easily-compressed documents such as DOC, XLS, and BMP files; it also contained a few small ZIP files for good measure. Zipped using Windows Explorer, the folder compressed to 8,881KB. 7-Zip compressed the same exact folder down to 6,036KB, shaving almost 3MB off the archive. Thats a difference of more than 25%--phenomenal, really, when you consider ZIPs market dominance. Speaking of market dominance, thats another key difference between the 7z and ZIP formats. Windows Explorer has been handling ZIP files like folders for years, and most people recognize read this them instantly and work with them all the time.

I googled my way to the answer to the question "Isn't there some way I can extract just the package I need from one of the Solaris iso.tar files using my Windows XP laptop?" The answer was "Yes, there is! It's called 7-Zip." 7-Zip is open source, GNU LGPL-licensed software that supports a extremely wide range of file formats. You can pack and unpack 7z, zip, gzip, bzip2 and tar files. You can unpack (i.e., unpack only) arj, cab, chm, cpio, deb, dmg, hfs, iso, lzh, lzma, msi, nsis, rar, rpm, udf, wim, xar and z files. What I needed was, of course, to download the iso.zip files from Sun's web site, unzip each of them (using 7-zip or WinZIP) and then find and extract the particular package that I needed using 7-zip. No CD burning needed. I found out that I could unzip and extract from the iso file with one running of 7-Zip. Here's how it worked: With 7-Zip installed on my laptop, I right clicked on the first of the Solaris iso.zip files. I then: selected 7-Zip -> Open Archive to open the iso.tar file double-clicked on the iso file opened the Solaris_10 folder opened the Product folder and looked through the package folders (e.g., SUNWfbc, SUNWfchba and so on) until I found the one I needed.
