If you have an archive file in your directory, go ahead and click on it. The command line is the only indication that you will have that you have been taken into the archive and are now viewing compressed files. Go ahead and view the files, copy them into other directories, etc. As you have probably noticed, you can click on a file in the Konqueror window and it will automatically either open it, start another tool, or ask you what to do with it. This is in part due to an extremely large selection of MIME types available to Konqueror.
MIME types tell an application what to do with specific types of files.
You can select and change the functionality of these MIME types from the KControl panel. If you are logged in as root it will also let you install the package or update your current version. The first screen you see shows you package information, such as version, date, descriptions, packager, and more. It will also let you upgrade, install, or erase if you are logged in as root. If you click on the second tab at the top of the screen you will see a list of files and the location of files installed in the package, as shown in Figure 2.
